Diagnostic Fault Information
Circuit | Short to Ground | Open/High Resistance | Short to Voltage | Signal Performance |
|---|---|---|---|---|
Intermittent Switch Signal | 1 | 2 | -- | -- |
Intermittent/Park Control | 1 | 5 | 3 | -- |
Wiper Motor Low Speed | 1 | 4 | 3 | -- |
1. Wipers Inoperative All Modes 2. Intermittent Wipers Inoperative 3. Wipers Always On 4. All Low Speed Modes Inoperative 5. Intermittent, Park, and Washer Wipers Inoperative | ||||
Circuit/System Description
Intermittent, park, and washer wipers are all low speed wiper motor functions controlled through the wiper relay integrated in the IP fuse block. During intermittent and wash operation the switch signals are inputs to the wiper relay. Whenever the relay is energized ignition voltage will be supplied from the relay through the windshield wiper switch to the wiper motor low speed circuit.

Circuit/System Verification
Ignition ON, verify the low speed windshield wipers operate.
| ⇒ | If the windshield wiper low speed function is inoperative, refer to Wipers Do Not Work on Low Speed. |
Circuit/System Testing
- Ignition OFF, disconnect the X1 harness connector at the IP fuse block.
- Wiper switch in the intermittent position, test for less than 5 Ω between the ignition circuit terminal 65 and the intermittent switch signal circuit terminal 31.
- If all circuits test normal replace the IP fuse block.
| ⇒ | If greater than the specified range, test the intermittent switch signal circuit terminal 31 for an open/high resistance. If the circuit tests normal replace the wiper switch. |
Repair Instructions
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.

Circuit/System Testing
- Ignition OFF, disconnect the harness connector at the wiper relay.
- Ignition ON wiper switch in the intermittent position, verify that a test lamp illuminates between the intermittent switch signal circuit terminal 1 and ground.
- If all circuits test normal replace the wiper relay.
| ⇒ | If the test lamp does not illuminate, test the intermittent switch signal circuit terminal 1 for an open/high resistance. If the circuit tests normal replace the wiper switch. |
