2. Replace Wiper Control Switch

Remove the steering column cover by unscrewing the screws that secure it.
Disconnect the wiring harness from the wiper control switch located on the steering column.
Remove the screws or clips holding the wiper control switch in place.
Install the new wiper control switch by reversing the removal steps, ensuring all connections are secure.

3. Replace Wiper Relay

Locate the fuse box (typically under the dashboard or in the engine compartment).
Identify the wiper relay based on the diagram on the fuse box cover.
Remove the faulty relay by pulling it out from its socket.
Install the new relay by pushing it firmly into place.
