Locate the fuse box under the dashboard or hood.
Identify the wiper relay according to the fuse diagram.
Remove the faulty relay and replace it with a new one.
Reassemble the fuse box cover.

4. Test Wiper Motor

Reconnect the battery terminal.
Activate the wipers to test functionality. If they still do not turn off, proceed to check the wiper control module.
