Solution

1. Preparation

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

Tools Required:

Socket set
Multimeter
OBD-II scanner
Wire connectors (if needed)

2. Inspect and Replace the Wiper Motor Fuse

Locate the fuse box (usually under the dashboard or hood).
Identify the fuse related to the windshield wipers using the diagram on the fuse box cover.
Use a fuse puller or appropriate tool to remove the wiper motor fuse.
Inspect the fuse for continuity. If blown, replace it with a new fuse of the same amperage.

3. Test the Wiper Motor

Reconnect the battery.
Using a multimeter, check for voltage at the wiper motor connector while activating the wiper switch.
If voltage is present but the motor does not operate, replace the wiper motor.

4. Replace the Wiper Motor (if necessary)

Remove the wiper arms by loosening the nut at the base of each arm using the socket set.
Remove the cowl cover to access the wiper motor.
Disconnect the wiring harness from the wiper motor.
Unscrew the wiper motor from its mount and remove it.
Install the new wiper motor in reverse order, ensuring all connections are secure and mounting bolts are torqued to specifications.

5. Reassemble and Test

Reinstall the cowl cover and wiper arms.
Test the wiper operation again to ensure functionality.
