Solution

1. Preparation

Tools Required:
- Socket set
- Multimeter
- Screwdrivers (flathead and Phillips)
- Pliers
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Replace Fuses

Locate the fuse box and identify the wiper fuse.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse; if blown, replace it with one of the same amperage.
Reconnect the battery and test the wipers.

3. Test and Replace Wiper Motor

Disconnect the wiper motor connector.
Use a multimeter to check for voltage at the connector while activating the wiper switch.
If there is no voltage, the issue may be with the switch or wiring; if voltage is present, proceed to replace the wiper motor.
Remove any mounting screws holding the motor in place, then disconnect the motor from the linkage.
Install the new motor and secure it with screws.

4. Inspect and Repair Wiper Linkage

Remove the wiper arms by loosening the retaining nuts and gently pulling the arms off the splines.
Inspect the linkage assembly for damage or disconnection.
If damaged, replace the linkage; if disconnected, reattach and ensure it is secured properly.

5. Replace Wiper Blades

Lift the wiper arms away from the windshield.
Release the blade from the arm by pressing the tab and sliding it off.
Slide the new wiper blade onto the arm until it clicks into place.
Lower the wipers back onto the windshield.
