Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to avoid electrical shorts during repair.
Ensure the vehicle is on a flat surface with the ignition turned off.

2. Inspect the Wiper Fuse

Locate the fuse box (consult the owner’s manual for the exact location).
Remove the wiper fuse using a fuse puller or needle-nose pliers.
Inspect the fuse for continuity; replace if blown.

3. Test the Wiper Motor

Access the wiper motor by removing the plastic cover from the base of the windshield (if applicable).
Disconnect the electrical connector from the wiper motor.
Using a multimeter, check for voltage at the connector while activating the wiper switch.
If voltage is present but the motor does not operate, replace the wiper motor.

4. Inspect the Wiper Linkage

Remove the wiper arms by loosening the retaining nuts using a socket set.
Carefully pull the wiper arms off the splines.
Inspect the linkage for any disconnections or damage; repair or replace as necessary.

5. Replace Wiper Blades (if needed)

Lift the wiper arm and depress the release tab on the wiper blade.
Slide the old blade off and replace it with a new one.
Ensure the new blade clicks into place securely.

6. Reassemble and Test

Reattach the wiper arms and tighten the retaining nuts to the manufacturer's specifications (usually around 10-15 ft-lbs).
Reconnect the battery and test the wiper operation.
If applicable, refill the washer fluid reservoir and test the washer pump.
