Solution

1. Preparation

Gather tools and parts.
Disconnect the battery to ensure safety during the repair.

2. Check and Replace the Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Use a fuse puller or pliers to remove the wiper fuse.
Inspect the fuse; if it is blown, replace it with a new fuse of the same amperage.
Reconnect the battery and test the wipers.

3. Test and Replace the Wiper Motor

If the fuse is intact, locate the wiper motor (usually near the base of the windshield).
Disconnect the motor's electrical connector.
Using a multimeter, check for voltage at the connector while activating the wiper switch.
If no voltage is present, troubleshoot wiring.
If voltage is present but the motor doesn’t operate, replace the wiper motor.
To replace, unbolt the motor from its mount, remove the linkage, and install the new motor in reverse order.

4. Inspect and Repair the Wiper Linkage

If the motor is working, check the wiper linkage for signs of wear or disconnection.
Remove the wiper arms from the splines on the motor shaft.
Disconnect the linkage from the motor and inspect for damage.
Replace any damaged components and reassemble.
