Motor Will Not Run In Any Switch Position
- Check fuse 5, in the Junction Block and fuse M in the Power Distribution Center and. Refer to WIPER/WASHER
for pin call outs.
- If fuse(s) are good, go to Step 2.
- If fuse(s) are defective replace, and check motor operation in all switch positions.
- If motor is still inoperative and the fuse does not blow, go to Step 2.
- If replacement fuse blows, go to Step 11
.
- Disconnect motor wire harness connector.
- Check the wiper motor low speed. Using two jumper wires, connect one jumper wire between the battery positive jump start terminal and Pin 2 on the wiper motor connector. Connect the other jumper wire to ground and Pin 5 on the wiper motor connector. Check the wiper motor high speed, connect the positive jumper wire to Pin 1 on the wiper motor connector. Connect the negative jumper wire to Pin 5 on the wiper motor connector.
- If motor runs, go to Step 4.
- If motor does not run, high or low speed replace the wiper motor.
- Using an ohmmeter, check for good ground at Pin 5 of the wiper motor wire harness connector. If not OK, repair the ground circuit as necessary. If OK, go to Step 5.
- Place the wiper switch in the ON position. Using a voltmeter, check for battery voltage at terminal D and A of the intermittent wiper relay in the Power Distribution Center. If no voltage check fuse M. If OK, go to Step 6. If not OK, repair as necessary.
- Using an ohmmeter, check from terminal D of the HI-LO wiper relay to Pin 1 of the motor wire connector for continuity. Check from terminal E of the HI-LO wiper relay to Pin 2 of the motor wire connector for continuity. If OK, go to Step 7. If not repair as necessary.
- Using an ohmmeter, check for continuity between the HI-LO wiper relay and the intermittent wiper relay. Check from terminal B of the HI- LO wiper relay to terminal B of the intermittent wiper relay. If OK, check for faulty relays and go to Step 8. If not repair as necessary.
- Disconnect the C3 bone 12-way connector from the BCM.
- Using an ohmmeter, check for continuity from terminal 4 of the BCM C3 24-way, black connector to the terminal C of the intermittent wiper relay. If OK, go to Step 10. If not repair as necessary.
- Using a voltmeter, connect positive lead to terminal 8 of the BCM C2 black 24-way connector and negative lead to ground. Turn ignition switch to the ON position. Slowly move, the wiper switch from OFF position through each position to HIGH.
- If voltage increases from zero to approximately 10 volts in the HIGH position, replace BCM. If no voltage, go to Step b.
- Using an ohmmeter, check for continuity from terminal 3 of wiper switch connector to terminal 8 of the BCM C2 black 24-way connector. If no continuity, repair circuit. If OK, go to Step c.
- Using a voltmeter, connect positive lead to terminal 1 of the wiper switch connector. If ignition voltage is present, replace the wiper switch. If no voltage, check continuity from fuse 5 to terminal 1 of the wiper switch connector. Repair circuit as necessary.
- Disconnect motor connector and replace fuse 5 from the Junction Block.
- If fuse does not blow, go to Step 2
.
- If fuse blows, wiper control circuit is at fault, repair as necessary, refer to WIPER/WASHER
