Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's 12V battery to ensure safety while working on electrical components.

2. Check and Replace the Fuse

Locate the fuse box (typically found under the dash or in the front trunk).
Remove the fuse for the windshield wipers using a fuse puller.
Inspect the fuse for continuity; if blown, replace it with a new fuse of the same amperage.

3. Inspect and Repair the Wiper Control Lever

Remove the steering column cover using a screwdriver or socket set.
Disconnect the wiring harness from the wiper control lever.
Inspect for any visible damage or corrosion.
If damaged, replace the wiper control lever with a new part.

4. Test and Replace the Wiper Motor

Locate the wiper motor, typically found near the base of the windshield.
Disconnect the motor’s electrical connector.
Using a multimeter, check for voltage at the connector when the wiper lever is activated.
If voltage is present but the motor does not operate, replace the wiper motor.
- To remove the motor, unbolt it from its mounting brackets and disconnect the linkage if applicable.

5. Reassemble and Test

Reconnect all components, including the wiper motor and control lever.
Reattach the steering column cover.
Reconnect the vehicle's 12V battery.
Test the windshield wipers to ensure they function correctly.
