Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the ignition off.
Disconnect the battery to avoid any electrical issues.

2. Check and Replace Fuse

Locate the fuse box (consult the owner’s manual for exact location).
Remove the wiper fuse using pliers or a fuse puller.
Inspect the fuse for any signs of damage; replace with the same amperage if necessary.

3. Test and Replace Relay

Locate the wiper relay in the fuse box (refer to the diagram on the cover).
Remove the relay and test it with a multimeter; if faulty, replace with a new relay.

4. Inspect and Test Wiper Motor

Disconnect the wiper motor connector.
Using a multimeter, check for power at the motor connector when the wiper switch is activated.
If power is present but the motor does not run, replace the wiper motor.
If no power, further investigate wiring and control stalk.

5. Reassemble and Reconnect

If any components were replaced, reassemble them in reverse order.
Reconnect the battery and ensure all connections are secure.
