Diagnostic Steps

1
Inspect the rear wiper fuse for continuity using a multimeter.
2
Check the rear wiper switch for proper function.
3
Test the voltage supply at the rear wiper motor connector.
4
Examine the wiring harness for any visible damage or disconnections.
5

Solution

1. Preparation

Gather all tools and parts required.
Park the vehicle on a flat surface and ensure it is in park mode.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect the Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the rear wiper fuse using a fuse puller or pliers.
Inspect the fuse for continuity. If blown, replace it with a fuse of the same amperage.

3. Check the Wiper Motor

Reconnect the battery terminal.
Remove the rear wiper arm by loosening the nut with a socket set and pulling it off the shaft.
Disconnect the wiring harness from the rear wiper motor.
Using a multimeter, check for voltage at the motor connector when the wiper switch is activated. If there is no voltage, further investigation is needed on the switch or wiring.

4. Test the Motor

If voltage is present, test the rear wiper motor by connecting it directly to the battery with jumper wires.
If the motor operates, it may require reinstallation; if not, it may need replacement.

5. Reassemble Components

If the motor tested good or was replaced, reattach the wiring harness.
Reinstall the wiper arm and tighten the nut to the manufacturer’s specified torque (typically around 10-12 ft-lbs).
Reconnect the negative battery terminal.
