CIRCUIT OPERATION
Fuse 10 in the fuse block powers the standard wiper system. The standard wiper system operates c either LOW or HIGH speeds.

In the ACCESSORY or RUN position, the ignition switch connects circuit A1 from fuse C in the Power Distribution Center (PDC) with circuit A31. Circuit A31 supplies voltage to circuit V6 through fuse 10 in the fuse block.

Circuit V6 splices to supply power to the wiper switch circuitry in the multi-function switch and to the park switch in the wiper motor. The wiper system is case grounded at the wiper motor.

When the operator moves the wiper switch to the LOW position, battery voltage passes through the switch to circuit V3. Circuit V3 feeds the wiper motor LOW speed brushes. If the operator selects wipe HIGH speed operation, the wiper switch passes current to circuit V4. Circuit V4 feeds the wiper motor HIGH speed brushes.

As the windshield wiper motor turns, the park switch, internal to the motor, moves from its DOWN position to the UP position. When the wiper switch is turned OFF, the V5 circuit prevents the wipers from stopping in any position but park.

The windshield washer uses a pump motor located inside the windshield washer fluid reservoir. When the washer switch is pressed, power is supplied through the wiper switch to the pump motor on circuit V10. Circuit Z1 provides ground for the pump motor. The Z1 circuit terminates at the left headlamp ground at the left fender side shield.
