Solution

1. Preparation

Gather tools: socket set, multimeter, flathead screwdriver, and replacement fuse (if needed).
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect and Replace Fuse

Locate the fuse box, usually found in the driver's side footwell or under the hood.
Remove the cover and find the rear wiper fuse (refer to the fuse diagram on the cover).
If the fuse is blown, replace it with a new fuse of the same amperage.
Reconnect the fuse box cover and the negative battery terminal.

3. Test Rear Wiper Switch

Remove the steering column cover using a flathead screwdriver.
Disconnect the wiring harness from the rear wiper switch.
Use a multimeter to check for continuity when the switch is engaged. If no continuity is present, replace the switch.

4. Inspect Wiring and Connectors

Follow the wiring from the rear wiper motor and check for any signs of wear, damage, or corrosion.
Clean any corroded connections with electrical contact cleaner.
Repair or replace damaged wiring or connectors as necessary.

5. Test and Replace Rear Wiper Motor (if needed)

Disconnect the wiper motor from the vehicle's wiring harness.
Using jumper wires, connect the motor directly to the battery to test its functionality.
If the motor does not operate, replace it with a new rear wiper motor by removing any mounting screws and disconnecting the wiper arm.
