The wiper high/low relay cannot be adjusted or repaired and, if faulty or damaged, the unit must be replaced.
OPERATION
The wiper high/low relay is an electromechanical switch that uses a low current input from the Front Control Module (FCM) to control a high current out- put to the wiper motor. The movable common feed contact point is held against the fixed normally closed contact point by spring pressure. When the relay coil is energized, an electromagnetic field is produced by the coil windings. This electromagnetic field draws the movable relay contact point away from the fixed normally closed contact point, and holds it against the fixed normally open contact point. When the relay coil is de-energized, spring pressure returns the movable contact point back against the fixed normally closed contact point. A resistor is connected in parallel with the relay coil in the relay, and helps to dissipate voltage spikes and electromagnetic interference that can be generated as the electromagnetic field of the relay coil collapses.

The wiper high/low relay terminals are connected to the vehicle electrical system through a connector receptacle in the Integrated Power Module (IPM). The inputs and outputs of the wiper high/low relay include: † Common Feed Terminal - The common feed terminal (30) is connected to the output of the wiper on/off relay at all times through the wiper on/off relay output circuit. † Coil Ground Terminal - The coil ground termi- nal (85) is connected to a control output of the Front Control Module (FCM) through a wiper high/low relay control circuit. The FCM controls wiper motor operation by controlling a ground path through this circuit. † Coil Battery Terminal - The coil battery ter- minal (86) receives battery current when the ignition switch is in the On or Accessory positions from a fuse in the Integrated Power Module (IPM) through a fused ignition switch output (run-acc) circuit. † Normally Open Terminal - The normally open terminal (87) is connected to the high speed brush of the wiper motor through a wiper high/low relay high speed output circuit, and is connected to the high speed brush whenever the relay is energized.
† Normally Closed Terminal
- The normally closed terminal (87A) is connected to the low speed brush of the wiper motor through a wiper high/low relay low speed output circuit, and is connected to the low speed brush whenever the relay is de-ener- gized.
The wiper high/low relay can be diagnosed using conventional diagnostic tools and methods. However, conventional diagnostic methods may not prove con- clusive in the diagnosis of the instrument cluster, the Front Control Module (FCM), or the electronic mes- sage inputs to or outputs from the instrument cluster and the FCM that control the operation of the wiper high/low relay. The most reliable, efficient, and accu- rate means to diagnose the wiper high/low relay, the instrument cluster, the FCM, or the electronic mes- sage inputs and outputs related to the wiper high/low relay operation requires the use of a DRBIIIt scan tool. Refer to the appropriate diagnostic information.

WIPER MODULE DESCRIPTION
The wiper motor bracket
is secured with two screws below the wiper motor through two rubber insulators to the bottom of the cowl plenum panel beneath the cowl plenum cover/grille panel (Fig. 25). Two screws secure the top of the wiper module bracket to the cowl plenum panel through rubber insulators located on the outboard end of each pivot bracket. The ends of the wiper pivot shafts that pro- trude through dedicated openings in the cowl plenum cover/grille panel to drive the wiper arms and blades are the only visible components of the wiper module. The wiper module consists of the following major components: † Bracket - The wiper module bracket consists of a long tubular steel main member that has a die cast

pivot bracket formation near each end where the two wiper pivots are secured. A stamped steel clamp secures the center of the tubular member to the die cast bracket integral to the wiper motor with two screws. † Crank Arm - The wiper motor crank arm is a stamped steel unit with a slotted hole on the driven end that is secured to the wiper motor output shaft with a nut, and has a ball stud secured to the drive end.† Linkage - Two stamped steel drive links con- nect the wiper motor crank arm to the wiper pivot lever arms. The left side drive link has a plastic sock- et-type bushing on each end. The right side drive link has a plastic socket-type bushing on one end, and a plastic sleeve-type bushing on the other end. The socket-type bushing on one end of each drive link is snap-fit over the ball stud on the lever arm of its respective pivot. The right side drive link sleeve- type bushing end is then fit over the motor crank arm ball stud, and the other socket-type bushing of the left side drive link is snap-fit over the exposed end of the wiper motor crank arm ball stud.
DR WIPER MODULE (Continued) † Motor - The wiper motor features an integral die cast bracket to which the wiper module bracket is secured with a stamped steel clamp and two screws near the top and which has two rubber insulated mounting ears at the bottom. This die casting also serves as the wiper motor transmission housing from which the wiper motor output shaft exits. A nut secures the wiper motor crank arm to the motor out- put shaft. The two-speed permanent magnet wiper motor features an integral transmission, an internal park switch, and an internal automatic resetting cir- cuit breaker. † Pivots - The two front wiper pivots are secured within the die cast pivot brackets on the outboard ends of the wiper module main member. The lever arms that extend from the center of the pivot shafts each have a ball stud on their end. The upper end of each pivot shaft where the wiper arms will be fas- tened each has a serrated driver with a keyway. The lower ends of the pivot shafts are installed through lubricated bushings in the pivot brackets and are secured with snap rings.
The wiper module cannot be adjusted or repaired. If any component of the module is faulty or damaged, the entire wiper module unit must be replaced.
OPERATION
The wiper module operation is controlled by the battery current inputs received by the wiper motor through the wiper on/off and wiper high/low relays. The wiper motor speed is controlled by current flow to either the low speed or the high speed set of brushes. The park switch is a single pole, single throw, momentary switch within the wiper motor that is mechanically actuated by the wiper motor transmission components. The park switch alter- nately opens and closes the wiper park switch sense circuit to ground, depending upon the position of the wipers on the glass. This feature allows the motor to complete its current wipe cycle after the wiper sys- tem has been turned Off, and to park the wiper blades in the lowest portion of the wipe pattern. The automatic the motor from overloads. The wiper motor crank arm, the two wiper linkage members, and the two wiper pivots mechanically convert the rotary output of the wiper motor to the back and forth wiping motion of the wiper arms and blades on the glass.

The wiper on/off relay is located in the Integrated Power Module (IPM) in the engine compartment near the battery. The wiper on/off relay is a conventional International Standards Organization (ISO) micro relay (Fig. 27). Relays conforming to the ISO specifi- cations have common physical dimensions, current capacities, terminal patterns, and terminal functions. The relay is contained within a small, rectangular, molded plastic housing and is connected to all of the required inputs and outputs by five integral male spade-type terminals that extend from the bottom of the relay base.
The wiper on/off relay cannot be adjusted or repaired and, if faulty or damaged, the unit must be replaced.
OPERATION
The wiper on/off relay is an electromechanical switch that uses a low current input from the Front Control Module (FCM) to control a high current out- put to the wiper motor. The movable common feed contact point is held against the fixed normally closed contact point by spring pressure. When the relay coil is energized, an electromagnetic field is produced by the coil windings. This electromagnetic field draws the movable relay contact point away from the fixed normally closed contact point, and holds it against the fixed normally open contact point. When the relay coil is de-energized, spring pressure returns the movable contact point back against the fixed normally closed contact point. A resistor is connected in parallel with the relay coil in the relay, and helps to dissipate voltage spikes and electromagnetic interference that can be generated as the electromagnetic field of the relay coil collapses.

to
Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of the page, and the ground (B-) side of the circuit is placed near the bottom of the page (Fig. 1).
All switches, components, and modules are shown in the at rest position with the doors closed and the key removed from the ignition (Fig. 2).
Components are shown two ways. A solid line around a component indicates that the component is complete. A dashed line around the component indi- cates that the component is being shown is not com- plete. components have a reference number to indicate the page where the component is shown complete.
Incomplete
It is important to realize that no attempt is made on the diagrams to represent components and wiring as they appear on the vehicle. For example, a short piece of wire is treated the same as a long one. In addition, switches and other components are shown as simply as possible, with regard to function only.
SYMBOLS
International symbols are used throughout the wir- ing diagrams. These symbols are consistent with those being used around the world (Fig. 3).

DESCRIPTION - SECTION IDENTIFICATION AND INFORMATION
The wiring diagrams are grouped into individual sections. If a component is most likely found in a par- ticular group, it will be shown complete (all wires, connectors, and pins) within that group. For exam- ple, the Auto Shutdown Relay is most likely to be found in Group 30, so it is shown there complete. It can, however, be shown partially in another group if it contains some associated wiring.
Splice diagrams in Section 8W-70 show the entire splice and provide references to other sections the splices serves. Section 8W-70 only contains splice dia- grams that are not shown in their entirety some- where else in the wiring diagrams.
Section 8W-80 shows each connector and the cir- cuits involved with that connector. The connectors are identified using the name/number on the dia- gram pages.

DIAGNOSIS AND TESTING - WIRING HARNESS
TROUBLESHOOTING TOOLS
When diagnosing a problem in an electrical circuit there are several common tools necessary. These tools are listed and explained below. † Jumper Wire - This is a test wire used to con- nect two points of a circuit. It can be used to bypass an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR, CONNECTED BETWEEN A BATTERY FEED AND GROUND.
† Voltmeter - Used to check for voltage on a cir- cuit. Always connect the black lead to a known good ground and the red lead to the positive side of the circuit.
CAUTION: Most of the electrical components used in today’s vehicles are Solid State. When checking voltages in these circuits, use a meter with a 10 - megohm or greater impedance rating.

Low or no resistance in a circuit means good continuity.factory items added to the vehicle before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify these add-on items are not the cause of the problem. (1) Verify the problem. (2) Verify any related symptoms. Do this by per- forming operational checks on components that are in the same circuit. Refer to the wiring diagrams.
(3) Analyze the symptoms. Use the wiring dia- grams to determine what the circuit is doing, where the problem most likely is occurring and where the diagnosis will continue.
(4) Isolate the problem area. (5) Repair the problem area. (6) Verify the proper operation. For this step, items on the
check for proper operation of all repaired circuit. Refer to the wiring diagrams.
STANDARD PROCEDURE
STANDARD PROCEDURE - ELECTROSTATIC DISCHARGE (ESD) SENSITIVE DEVICES
All ESD sensitive components are solid state and a symbol (Fig. 6) is used to indicate this. When han- dling any component with this symbol, comply with the following procedures to reduce the possibility of electrostatic charge build up on the body and inad- vertent discharge into the component. If it is not known whether the part is ESD sensitive, assume that it is.
(1) Always touch a known good ground before han- dling the part. This should be repeated while han- dling the part and more frequently after sliding across a seat, sitting down from a standing position, or walking a distance.
(2) Avoid touching electrical terminals of the part,
unless instructed to do so by a written procedure.
(3) When using a voltmeter, be sure to connect the
ground lead first.
(4) Do not remove the part form it’s protective
packing until it is time to install the part.
(5) Before removing the part from it’s pakage, ground the pakage to a known good ground on the vehicle.
CAUTION: Most of the electrical components used in today’s vehicles are Solid State. When checking resistance in these circuits use a meter with a 10 - megohm or greater impedance rating. In addition, make sure the power is disconnected from the cir- cuit. Circuits that are powered up by the vehicle’s electrical system can cause damage to the equip- ment and provide false readings. † Probing Tools - These tools are used for probing terminals in connectors (Fig. 5). Select the proper size tool from Special Tool Package 6807, and insert it into the terminal being tested. Use the other end of the tool to insert the meter probe.

2 - PROBING ENDINTERMITTENT AND POOR CONNECTIONS
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also possible for a sticking component or relay to cause a problem. Before condemning a component or wiring assembly, check the following items. † Connectors are fully seated † Spread terminals, or terminal push out † Terminals in the wiring assembly are fully seated into the connector/component and locked into position † Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent problem † Damaged connector/component casing exposing † Wire insulation that has rubbed through causing † Some or all of the wiring strands broken inside † Wiring broken inside of the insulation TROUBLESHOOTING WIRING PROBLEMS
