Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to ensure safety.

2. Replace Wiper Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the wiper fuse using a fuse puller or pliers.
Inspect the fuse; if blown, replace it with a new one of the same amperage (typically 15A).

3. Test and Replace Wiper Motor

Reconnect the negative battery terminal.
Using a multimeter, check for power at the wiper motor harness while activating the wiper switch.
- If power is present, the motor likely needs replacement.
If no power is present, trace back to the relay.

4. Check and Replace Wiper Relay

Locate the wiper relay in the fuse box or relay panel.
Pull the relay and use a multimeter to test for continuity. Replace if faulty.

5. Inspect and Replace Wiper Control Switch

Remove the steering column cover to access the wiper control switch.
Disconnect the switch harness and test for continuity with a multimeter.
If defective, replace with a new switch.
