Motor Won't Run In Any Switch Position

Wiper Motor Wiring Connectors:

NOTE: To gain access to wiper motor wiring terminals, remove terminal cover or suppressor as required.

1. Check fuse block for blown wiper fuse:
a. If fuse is good, go to step 2.
b. If fuse is blown, replace and check motor operation in all switch positions.
c. If motor is still inoperative and new fuse does not blow, go to step 2.
d. If new fuse blows, go to step 5.
2. Place switch in low speed position.
3. If you cannot hear motor running, go to step 4. If motor is running, check output shaft. If shaft is not turning, replace motor assembly. If shaft is turning, drive link to output shaft or linkage is not properly connected. Replace worn parts and/or properly connect drive link to motor output shaft.

Voltmeter Between Terminal "L" And Ground:

4. Connect a voltmeter or test lamp between motor terminal "L" and ground strap. If there is no voltage, check wiring and switch. If there is approximately 12V at terminal "L" or test lamp lights, problem is:
a. An open ground circuit. Ensure that motor mounting is free of paint and nuts are tight.
b. Faulty motor assembly.
5. Disconnect motor wiring connector and replace fuse.
a. If fuse does not blow, motor is defective.
b. If fuse blows, switch or wiring is faulty.
