Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and turn off the engine.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuse

Locate the fuse box and find the wiper fuse (refer to the owner's manual for the exact location).
Remove the fuse using a fuse puller and inspect it for continuity.
If blown, replace it with a new fuse of the same amperage.

3. Test and Replace Wiper Motor

Reconnect the battery and use a multimeter to test for voltage at the wiper motor connector while activating the wiper switch.
If there is voltage but the motor does not operate, proceed to remove the wiper motor:
1. Remove the wiper arms by loosening the retaining nuts with a socket set.
2. Remove the cowl panel to access the wiper motor.
3. Disconnect the wiring harness from the motor.
4. Remove the mounting bolts securing the motor and take it out.
Install the new wiper motor by reversing the removal steps, ensuring all connections are secure.

4. Inspect and Repair Wiper Linkage

With the motor removed, inspect the wiper linkage for wear or damage.
If necessary, lubricate the linkage or replace any faulty components.
Ensure the linkage is properly connected before reassembling.
