Wiper Completely Inoperative
- Connect test lamp between ground and motor terminal 2. If no power, check fuse and feed wire. If power is present, connect test lamp to terminal 1. If no power, replace park relay. If power is present at terminal 1, move wiper switch to "LO" and disconnect wiper plug from terminals 1, 2, 3.
- Connect test lamp between sockets in connector for terminals 1 and 2. If lamp does not light, check for open circuit in terminal 1 wire to switch, then check switch ground and switch. Place dash switch in "HIGH" position.
- Disconnect wiring from terminal 6. Connect one lead of test lamp to positive battery terminal or 12V source, and connect the other end to terminal 6 wire in connector. If no power, check for open in terminal 6 wire to switch and check switch. If power is present, remove washer pump cover and reconnect all wiring to motor.
- Place dash switch in "LOW" position. Connect test lamp to ground and probe red wire at pulse relay. If no power, replace park relay. If power is present, connect a jumper wire from pulse relay orange wire terminal to ground. If motor runs, replace timer/switch assembly.
- If motor did not run, leave jumper connected and connect test lamp to ground and probe black/pink wire at pulse relay. If power is present, motor is faulty and must be repaired. If no power, replace pulse relay.
