Locate the fuse box, usually found under the dashboard or in the engine compartment.
Identify the fuse for the rear wiper (refer to the owner's manual for the specific location).
Remove the fuse using a fuse puller or pliers to avoid damage.
Inspect the fuse and replace it if blown with a new fuse of the same amperage.

3. Test the Rear Wiper Motor

Reconnect the battery.
Activate the rear wiper switch.
Use a multimeter to check for voltage at the rear wiper motor connector.
If voltage is present, proceed to remove the wiper motor. If not, further diagnose the switch or wiring.
