Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and basic hand tools.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the 12V battery to prevent electrical shock while working on the system.

2. Inspect and Replace Fuse

Locate the fuse box (refer to the owner's manual for exact location).
Remove the wiper fuse using a fuse puller or pliers.
Inspect the fuse for any signs of damage or breakage.
If blown, replace with a new fuse of the same amperage.

3. Check Wiper Motor Connections

Reconnect the battery and inspect the wiper motor's electrical connector.
Disconnect the wiper motor connector and check for corrosion or loose connections.
Clean the connector with electrical contact cleaner if necessary.
Reconnect the motor to ensure a secure fit.

4. Test and Replace Wiper Motor (if required)

If the wiper motor did not operate during the direct power test, it may need replacement.
Remove the wiper arms by unscrewing the retaining nuts and lifting them off the splines.
Unbolt the wiper motor from its mounting points.
Install the new wiper motor by reversing the removal process and ensuring all bolts are torqued to manufacturer specifications.

5. Final Assembly

Reattach the wiper arms in the correct position.
Reconnect the battery.
Test the wipers to ensure they are functioning properly.
