Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's 12V battery to ensure safety.
Tools Required: Socket set, screwdriver set, multimeter, OBD-II scanner (if needed).

2. Inspect and Clean Connections

Locate the wiper motor assembly, usually found under the cowl panel at the base of the windshield.
Remove any covers or trim pieces to access the motor.
Inspect the electrical connections for corrosion or damage.
Clean the connections using electrical contact cleaner and reconnect securely.

3. Check the Fuse

Locate the fuse box and identify the fuse connected to the windshield wipers (refer to the owner’s manual for specific fuse location).
Remove the fuse and inspect it for continuity using a multimeter. If the fuse is blown, replace it with one of the same rating.

4. Test the Wiper Motor

Using a multimeter, check the voltage at the wiper motor connector while activating the wipers from inside the vehicle.
If voltage is present but the motor does not operate, the motor may need replacement.
If no voltage is detected, trace the wiring back to identify any breaks or shorts.

5. Replace the Wiper Motor (if necessary)

If the motor is faulty, disconnect the motor from its electrical connector.
Remove the mounting bolts securing the motor to the vehicle.
Install the new wiper motor in reverse order of removal, ensuring all connections are secure.
Reconnect the battery and test the wipers.
