Solution

1. Preparation

Tools Required: Socket set, multimeter, flathead screwdriver, pliers
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace the Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Find the wiper fuse (refer to the fuse diagram on the cover).
Use a fuse puller or pliers to remove the fuse.
Inspect the fuse for a break in the filament. If blown, replace with a new fuse of the same amperage.

3. Inspect and Test the Wiper Motor

Remove the wiper arms by loosening the nut using a socket set and gently lifting them off the splines.
Disconnect the wiper motor connector.
Set the multimeter to measure voltage and connect the leads to the motor terminals.
Activate the wipers and check for power at the motor connector. If no power is present, troubleshoot the wiring or switch.

4. Examine and Repair Wiper Linkage

Visually inspect the wiper linkage assembly for any disconnections or bent components.
If the linkage is damaged or disconnected, reattach it or replace any broken parts as necessary.

5. Replace Wiper Blades

Lift the wiper arms and press the release tab on the wiper blade to detach it from the arm.
Attach the new wiper blades by sliding them into place until you hear a click.
Ensure they are securely fastened, then lower the wiper arms back to the windshield.

6. Test the Washer Fluid Pump

Locate the washer fluid reservoir and check the fluid level.
Disconnect the pump connector and apply direct power to the pump to verify operation.
If the pump does not operate, replace it with a new unit.
