Solution

1. Preparation

Tools Required: Socket set, multimeter, flathead screwdriver, pliers, safety gloves
Gather necessary parts for replacement (if needed) such as a new wiper motor or fuse.

2. Check and Replace the Fuse

Locate the fuse box (refer to the owner's manual for the exact location).
Remove the cover and identify the wiper fuse using the diagram on the fuse box lid.
Use a multimeter to check for continuity in the fuse. If blown, replace it with one of the same amperage.

3. Inspect and Replace the Wiper Motor

Disconnect the negative battery terminal to ensure safety.
Remove the wiper arms using a flathead screwdriver to pry off the caps and a socket wrench to unbolt the arms from the motor.
Unplug the wiper motor connector and remove the mounting bolts securing the motor.
Compare the old motor with the new one to ensure compatibility, then install the new motor in reverse order of removal.
Reconnect the battery terminal.

4. Check and Repair Wiper Linkage

If the wiper motor is operational but wipers are still not moving, inspect the wiper linkage.
Remove the wiper motor again if necessary to gain access to the linkage.
Ensure all connections are tight and that there is no rust or damage. Lubricate moving parts if necessary.
Reassemble the components once repairs are made.

5. Test the Washer Fluid Pump

Locate the washer fluid reservoir and inspect the pump.
Disconnect the pump connector and apply direct power to see if it operates.
If the pump is faulty, replace it with a new unit.
