Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety during the repair.
Tools Required: Socket set, multimeter, flathead screwdriver, and pliers.

2. Inspect and Replace Wiper Fuse

Locate the fuse box (usually found under the dashboard or in the engine compartment).
Remove the cover and find the wiper fuse (refer to the diagram on the cover).
Use a multimeter to check for continuity in the fuse.
If the fuse is blown, replace it with a fuse of the same amperage (typically 10A or 15A).

3. Check Wiper Motor Connections

Remove the wiper arm by loosening the nut with a socket set and carefully pulling it off.
Disconnect the wiring harness from the wiper motor.
Inspect for any corrosion or loose connections. Clean or repair as necessary.

4. Test the Wiper Motor

With the harness disconnected, use a multimeter to check the voltage at the motor terminals while activating the wipers.
If voltage is present but the motor does not operate, replace the wiper motor.
If no voltage is present, trace back to the wiper switch or wiring harness.

5. Replace Wiper Motor (if necessary)

Remove any mounting screws securing the wiper motor.
Carefully pull out the motor from its housing.
Install the new wiper motor in reverse order, ensuring it is properly mounted and secured.
Reconnect the wiring harness.

6. Reassemble and Test

Reattach the wiper arm and secure it with the nut.
Reconnect the negative battery terminal.
Activate the wipers to ensure they function correctly.
