Solution

1. Preparation

Gather tools: socket set, multimeter, screwdriver set.
Disconnect the negative terminal of the battery for safety.

2. Inspect Wiper Assembly

Remove the wiper arms using a puller tool if necessary.
Check for damaged or worn wiper blades and replace if needed.
Ensure the wiper linkage is not damaged or disconnected.

3. Replace Fuse

Locate the fuse box and remove the cover.
Identify the wiper fuse (refer to the owner's manual for the exact location).
Replace the fuse if it is blown. Use the same amperage rating as specified.

4. Test and Replace Wiper Motor (if necessary)

Reconnect the battery and check for voltage at the wiper motor connector using the multimeter.
If no voltage is present, suspect a faulty control switch or wiring issue.
If voltage is present but the motor does not operate, remove the motor:
- Unscrew the motor mounting bolts.
- Disconnect the electrical connector.
Install the new wiper motor, ensuring it is securely mounted and connected.

5. Reassemble and Test

Reattach the wiper arms in the correct position.
Reconnect the battery and test the wipers for operation in all modes.
