Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent electrical shock and accidental activation of the wipers.

2. Inspect Wiper Control Stalk

Remove the steering column covers using a screwdriver.
Disconnect the wiper control stalk connector.
Use a multimeter to test for continuity in the stalk’s position switches.
Replace the wiper control stalk if any switches are faulty.

3. Check Wiper Relay

Locate the wiper relay in the fuse box.
Remove the relay and test it with a multimeter for proper operation.
If defective, replace with a new relay of the same specifications.

4. Inspect Wiring and Connections

Visually inspect the wiring harness leading to the wiper motor for damage or corrosion.
Clean any corroded connections with electrical contact cleaner.
Repair or replace any damaged wiring as necessary.

5. Test Wiper Motor

Reconnect the battery and activate the wipers.
Measure voltage at the wiper motor connector using a multimeter.
If no voltage is present when the wipers should be off, the BCM may need to be diagnosed or replaced.
