Solution

1. Preparation

Gather tools and parts before starting the repair.
Disconnect the battery to avoid any electrical shorts.
Tools Required: Socket set, multimeter, wire stripper/crimper, and a flathead screwdriver.

2. Check and Replace Fuse

Locate the fuse box and find the fuse for the windshield wipers.
Remove the fuse using the fuse puller or pliers.
Inspect the fuse for continuity; replace it if it is blown.
Reinsert the new fuse back into its slot.

3. Inspect and Repair Wiring and Connections

Remove any protective covers to access the wiring harness connected to the wiper motor.
Visually inspect the wiring for any signs of wear, damage, or corrosion.
If damaged, use a wire stripper to expose fresh wire and crimp on new connectors to repair.
Ensure all connections are tight and free of corrosion.

4. Test Wiper Motor

Disconnect the wiper motor connector.
Use a multimeter to check for voltage at the connector while activating the wiper switch.
If voltage is present but the motor does not operate, replace the wiper motor.
If no voltage is detected, further diagnose the switch and relay.

5. Replace Wiper Motor (if necessary)

Remove the wiper arm by lifting the cap and unscrewing the nut holding it in place.
Disconnect the wiring harness from the wiper motor.
Remove the mounting screws for the wiper motor and carefully pull it out.
Install the new wiper motor by reversing the removal steps, ensuring a secure fit.
