Solution

1. Preparation

Gather tools and parts needed.
Disconnect the negative terminal of the battery to ensure safety during repairs.

2. Inspect the Wiper Control Stalk

Remove the steering column cover using a screwdriver or socket set.
Disconnect the wiring harness from the wiper control stalk.
Inspect the stalk for any signs of physical damage or corrosion.
If faulty, replace the wiper control stalk with a new one.

3. Check the Fuses

Locate the fuse box (refer to the owner’s manual for location).
Remove the fuse for the wipers using a fuse puller or pliers.
Inspect the fuse visually; replace it if blown.
Reinsert the fuse and ensure it is seated properly.

4. Test the Wiper Motor

Reconnect the battery terminal.
Use a multimeter to check voltage at the wiper motor connector while operating the wiper control stalk.
If no voltage is detected, trace back to the wiring or BCM for further issues.
If voltage is present but the motor does not operate, replace the wiper motor.

5. Inspect Wiring and Ground Connections

Visually inspect wiring harnesses for fraying, corrosion, or loose connections.
Use a multimeter to verify continuity of the ground wire connected to the wiper motor.
Repair any damaged wiring or connections found during inspection.
