Solution

1. Preparation

Gather tools and materials: OBD-II scanner, multimeter, socket set, wire strippers, electrical tape, and replacement fuses or wiper motor if necessary.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Check and Replace Wiper Fuse

Locate the fuse box: Refer to the owner's manual to find the location of the fuse box.
Remove the fuse: Use a fuse puller or pliers to remove the wiper fuse.
Inspect the fuse: Check if the metal wire inside the fuse is broken.
Replace if necessary: If the fuse is blown, replace it with one that matches the amperage rating (typically 10A or as specified in the manual).
Reinstall the fuse: Put the new fuse back into its slot securely.

3. Test Wiper Motor

Access the wiper motor: Remove the plastic cover from the wiper assembly, typically secured with clips or screws.
Disconnect the motor connector: Unplug the wiper motor wiring harness.
Apply direct power: Using jumper wires, connect the positive wire to the positive terminal of the battery and the negative wire to the ground.
Observe motor operation: If the motor activates, it is functioning properly; if not, it may need replacement.

4. Inspect Wiring and Connectors

Visual inspection: Look for any frayed wires, corrosion, or loose connections in the wiper motor circuit.
Repair as needed: Use wire strippers to remove damaged sections and splice in new wire. Secure with electrical tape or heat-shrink tubing.

5. Reassemble

Reattach the wiper motor: If operational, reconnect the wiring harness and mount the motor back in its original location.
Reinstall wiper arms: Align and secure the wiper arms back onto the spindle, ensuring they are positioned correctly for operation.
Replace any covers: Put back any plastic covers removed during access.
