Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety during repairs.

2. Check and Replace the Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the wiper fuse using the fuse diagram.
Remove the fuse and inspect it for continuity. If blown, replace it with a new fuse of the same amperage.

3. Inspect and Replace the Wiper Relay

Locate the wiper relay in the fuse box or relay panel.
Remove the relay and inspect for any visible damage.
Replace with a new relay if necessary.

4. Test the Wiper Motor

Reconnect the battery.
Use a multimeter to check for voltage at the wiper motor connector (typically 12 volts).
If voltage is present and the motor does not operate, remove the motor from its mounting:
- Disconnect the electrical connector.
- Remove the mounting bolts.
- Pull the motor out carefully.
Test the motor by applying direct battery voltage to it. If it does not run, replace it.

5. Check the Wiper Switch

Remove the steering column cover to access the wiper switch.
Disconnect the wiring harness from the switch and test for continuity using a multimeter.
If defective, replace the wiper switch.
