Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle battery to ensure safety during repairs.

2. Check and Replace the Fuse

Locate the fuse box (refer to the owner's manual for location).
Identify the wiper fuse and remove it using a fuse puller.
Inspect the fuse; if it is blown, replace it with a new fuse of the same amperage.
Reconnect the battery and test the wipers.

3. Inspect and Replace the Wiper Motor

If the fuse is intact, access the wiper motor by removing the plastic cowl covering it.
Disconnect the electrical connector from the wiper motor.
Use a multimeter to check for voltage at the motor connector while activating the wiper switch.
If no voltage is detected, trace wiring back to the switch for continuity; repair if necessary.
If voltage is present but the motor does not operate, replace the wiper motor:
- Remove the retaining bolts using a socket set.
- Disconnect the motor from the linkage.
- Install the new wiper motor and reconnect the electrical connector.
- Secure the motor with bolts and reattach the cowl.

4. Repair or Replace Wiper Linkage

If the wipers move erratically, inspect the linkage:
- Remove any covers or panels to access the linkage.
- Look for any bent or disconnected parts.
- If necessary, remove the linkage by unfastening the bolts and replace it with a new one.
- Reassemble by securing all bolts and covers.

5. Replace Wiper Blades

If the blades are worn, replace them:
- Lift the wiper arm away from the windshield.
- Press the release tab on the blade and slide it off the arm.
- Attach the new blade by sliding it onto the arm until it clicks into place.
- Repeat for the other blade.
