Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Inspect and Replace Fuses

Tools Required: Fuse puller or pliers
Locate the fuse box, typically found under the dashboard or in the front trunk.
Identify the wiper fuse using the fuse diagram (usually labeled).
Remove the fuse and inspect it for continuity; replace if blown with an appropriate fuse (typically 10A or as specified in the manual).

3. Check Wiper Motor Connections

Tools Required: Socket set, multimeter
Remove the wiper arm covers to access the mounting bolts.
Unbolt and lift the wiper arms off for better access to the motor.
Disconnect the wiring harness from the wiper motor and inspect for corrosion or damage.
Use a multimeter to check for continuity in the motor's connectors.

4. Test the Wiper Motor

Tools Required: Jumper wires
Connect jumper wires from a 12V source directly to the wiper motor terminals.
Observe if the motor operates; if it does not, the motor may need replacement.
If it operates, reconnect the wiring and proceed to test the control system again.

5. Software Update

Use the touchscreen interface to check for software updates.
Install any available updates that may resolve control issues with the wiper system.
