Solution

1. Preparation

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

Tools Required:

Multimeter
OBD-II scanner
Socket set
Screwdrivers
Pliers

2. Check and Replace Fuse

Locate the fuse box (refer to the owner's manual for exact location).
Remove the cover and locate the windshield wiper fuse.
Use a fuse puller or pliers to remove the fuse.
Inspect the fuse; if it is blown, replace it with a new fuse of the same amperage.
Reinstall the fuse box cover.

3. Test the Wiper Motor

Reconnect the battery.
With the multimeter, check for voltage at the wiper motor connector by activating the wiper switch.
If there is no voltage, the wiper switch or wiring may be faulty.
If voltage is present but the motor does not activate, replace the wiper motor.

4. Inspect and Repair Wiper Linkage

Remove the wiper arms using a socket set (ensure the wipers are in the "off" position).
Disconnect the wiper motor connector.
Remove the wiper linkage assembly by unscrewing the mounting bolts.
Inspect for any broken or disconnected components; replace as necessary.
Reinstall the linkage assembly and reconnect the wiper motor.

5. Reinstall Wiper Arms

Position the wiper arms back onto the splines and secure them using the socket set.
Ensure they are aligned correctly for optimal performance.
