Solution

1. Preparation

Tools Required: Socket set, multimeter, flat-head screwdriver, pliers
Disconnect the negative terminal of the battery to ensure safety during repairs.

2. Check and Replace Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Refer to the owner’s manual for the specific fuse for the windshield wipers.
Remove the fuse using pliers or a fuse puller.
Inspect the fuse for continuity; replace it if blown with one of the same amperage (usually 15A or 20A).

3. Wiper Motor Inspection

Remove the wiper arms by loosening the nut with a socket wrench and lifting them off the splines.
Disconnect the wiper motor wiring harness.
Use a multimeter to check for voltage at the motor connector while activating the wiper switch; it should read around 12 volts.
If no voltage is present, trace back to the switch or look for wiring issues.

4. Replace Wiper Motor (if necessary)

If the motor is faulty, remove the mounting screws with a socket set.
Carefully lift the motor out, ensuring not to damage the linkage.
Install the new wiper motor in reverse order and secure it with screws.
Reconnect the wiring harness.

5. Reassemble and Test

Reattach the wiper arms to their respective positions.
Tighten the nuts securely without over-tightening to avoid damage.
Reconnect the negative battery terminal.
Test the wipers to ensure they operate smoothly and effectively.
