Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, screwdrivers, and a replacement wiper motor or control stalk if needed.
Disconnect the 12V battery to ensure safety while working on electrical components.

2. Check and Replace the Wiper Fuse

Locate the fuse box, typically found under the dashboard or in the trunk.
Remove the cover of the fuse box and identify the wiper fuse using the fuse diagram.
Pull the wiper fuse out with a fuse puller or pliers and inspect it for continuity.
If the fuse is blown, replace it with a fuse of the same amperage (check vehicle manual for specific rating).

3. Wiper Motor Inspection and Replacement

Reconnect the battery and activate the wipers to see if they work.
If they do not, proceed to remove the wiper arms using a socket set to unscrew the nuts holding them in place.
Disconnect the wiper motor by unplugging the electrical connector and removing any mounting bolts.
Install the new wiper motor by reversing the removal steps: secure the mounting bolts, reconnect the electrical connector, and reinstall the wiper arms.

4. Test and Verify System Functionality

Reconnect the battery and test the wipers at all speeds.
Check for proper wiper fluid spray functionality.
