Solution

1. Preparation

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

2. Inspect and Replace Wiper Control Switch

Remove the steering column cover to access the wiper control switch.
Disconnect the wiring harness from the switch.
Remove the screws holding the switch in place and carefully take it out.
Install the new wiper control switch by reversing the removal steps and reconnecting the wiring harness.

3. Test and Replace Wiper Motor (if needed)

If the motor did not operate during testing, remove the wiper arms by unscrewing the retaining nuts.
Remove the wiper motor by unscrewing the mounting bolts.
Disconnect the electrical connector from the motor.
Install the new wiper motor by reversing the removal steps, ensuring all connections are secure.

4. Check and Replace Wiper Relay

Locate the wiper relay in the fuse box.
Remove the relay and inspect it for any signs of burning or damage.
If defective, replace it with a new relay of the same specifications.

5. Reassemble and Test

Reassemble any components removed (steering column cover, wiper arms).
Reconnect the battery, and test the wipers to ensure they function correctly.
