Solution

1. Preparation

Gather necessary tools: screwdrivers, multimeter, socket set, and replacement fuses or wiper motor if needed.
Disconnect the vehicle battery to ensure safety while working on the electrical system.

2. Check and Replace Fuses

Locate the fuse box, typically under the dashboard or in the engine compartment.
Identify the fuse associated with the windshield wipers using the fuse diagram.
Remove the fuse using a fuse puller or needle-nose pliers. Inspect for continuity.
If blown, replace with a fuse of the same amperage (consult owner's manual for specifications).

3. Test and Replace Wiper Motor (if necessary)

Reconnect the battery and switch the wipers on.
Use a multimeter to check for voltage at the wiper motor connector; it should read between 12-14 volts.
If no voltage is detected, further investigate the wiring or switch.
If voltage is present but the motor does not operate, remove the wiper arms by loosening the retaining nuts.
Unscrew the wiper motor from its mount using a socket set.
Disconnect the wiring harness and remove the motor from the vehicle.
Install the new wiper motor by reversing the removal steps and ensure it is securely fastened.

4. Reassemble and Test

Reattach the wiper arms and secure them with the retaining nuts.
Reconnect the battery and test the wipers to ensure they function correctly.
