Windshield Wiper Control Unit/Motor Input Test
NOTE: Make sure the fuses associated with the system is OK.
1. Turn the vehicle to the OFF (LOCK) mode.
2. Disconnect the windshield wiper control unit/motor 6P connector.
Windshield Wiper Control Unit/Motor 6P Connector (female terminals)
Inspect the connectors and socket terminals to be sure they are all making good contact:
- If the terminals are bent, loose, or corroded, repair them as necessary, and recheck the system.
- If the terminals are OK, go to step 4.
With the connectors still disconnected, do the following input tests:
- If any test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, go to step 5.
| Cavity | Wire | Test condition | Test: Desired result | Possible cause if desired result is not obtained |
|---|---|---|---|---|
| 3 | PUR | Disconnect body control module connector B (36P) | Check for continuity between terminal No. 3 and body control module connector B (36P) terminal No. 10: There should be continuity. | An open or high resistance in the wire |
| 4 | PNK | Disconnect body control module connector C (28P) | Check for continuity between terminal No. 4 and body control module connector C (28P) terminal No. 13: There should be continuity. | An open or high resistance in the wire |
Reconnect the windshield wiper control unit/motor 6P connector, and do the following input tests:
- If any test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, Replace the windshield wiper control unit/motor .
| Cavity | Wire | Test condition | Test: Desired result | Possible cause if desired result is not obtained |
|---|---|---|---|---|
| 2 | BLU | Under all conditions | Measure the voltage to ground: There should be battery voltage. | An open or high resistance in the wire |
| 1 | BLK | Under all conditions | Measure the voltage to ground: There should be less than 0.2 V. |
