2
Check the wiper fuse in the fuse box for continuity.
3
Test the wiper motor voltage using a multimeter while operating the switch.
4
Examine the wiper linkage and arms for any binding or mechanical issues.

Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the battery to prevent any electrical shorts.
Ensure the vehicle is parked on a level surface with the ignition off.

2. Check and Replace Wiper Fuse

Locate the fuse box (refer to the owner's manual for the exact location).
Remove the cover and identify the wiper fuse.
Use a fuse puller to remove the fuse and check for continuity.
- If the fuse is blown, replace it with a fuse of the same amperage (typically 20A).
Reinstall the fuse and cover, reconnect the battery.

3. Inspect and Replace Wiper Motor

Remove the wiper arms by loosening the nut securing them (use a socket set).
Disconnect the wiring harness from the wiper motor.
Unbolt the wiper motor from its mounting bracket.
Install the new wiper motor by reversing the removal steps. Ensure all connections are secure.
Torque the mounting bolts to the manufacturer’s specifications (usually around 10-15 ft-lbs).

4. Test Wiper Functionality

Reconnect the battery.
Turn on the ignition and test the windshield wipers on all settings.
Ensure they operate smoothly and park correctly when turned off.
