Solution

1. Preparation

Tools Required: Socket set, multimeter, torque wrench, flathead screwdriver.
Disconnect the vehicle’s battery to ensure safety during electrical work.

2. Inspect and Replace the Fuse

Locate the fuse box, usually found under the dashboard or in the trunk area.
Identify the fuse responsible for the windshield wipers (refer to the vehicle's manual).
Remove the fuse using a fuse puller or flathead screwdriver.
Inspect the fuse for damage; replace it if blown with an equivalent amperage fuse.

3. Check Wiper Motor and Wiring

Remove the wiper arms using a socket set and carefully lift them off the motor.
Disconnect the wiring harness from the wiper motor.
Using a multimeter, test for voltage at the motor connector while someone activates the wiper switch.
If no voltage is present, trace the wiring back to the fuse box for damage or disconnection.
If voltage is present but the motor does not operate, replace the wiper motor.

4. Reassemble and Test

Reattach the wiring harness to the new or repaired wiper motor.
Reinstall the wiper arms and secure with the appropriate torque.
Reconnect the vehicle’s battery.
Test the wipers by activating the control stalk to ensure functionality.
