Solution

1. Preparation

Gather tools: socket set, multimeter, OBD-II scanner, screwdriver set, and replacement parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to prevent electrical shorts.

2. Replace Wiper Fuse

Locate the fuse box (refer to the owner’s manual for location).
Identify the wiper fuse and remove it using a fuse puller or pliers.
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 Wiper Motor

Remove the wiper arms: use a flat-head screwdriver to gently pry off the caps, then use a socket to remove the nuts.
Disconnect the wiring harness from the wiper motor.
Remove the motor by unscrewing its mounting bolts.
Install the new wiper motor by reversing the removal steps and ensuring all connections are secure.

4. Check and Replace Wiper Linkage (if needed)

If the wipers still do not operate properly, inspect the wiper linkage.
Remove the wiper motor as described above.
Check the linkage for signs of wear or breaks; replace if necessary.
Reassemble everything by reversing the steps.

5. Final Assembly

Reattach the wiper arms securely and ensure they are aligned correctly.
Reconnect the battery and test the wipers again.
