Solution

1. Preparation

Tools Required:
- Socket set
- Multimeter
- OBD-II scanner (if error codes are present)
- Flat-head screwdriver
Disconnect the vehicle's 12V battery to ensure safety during repairs.

2. Inspect and Replace the Fuse

Locate the fuse box, typically found under the dashboard or in the trunk.
Remove the cover and identify the wiper fuse (refer to the fuse diagram).
Using a fuse puller or pliers, remove the fuse and inspect it for continuity.
- If blown: Replace it with a fuse of the same rating (check the owner’s manual for specifications).

3. Check and Repair the Wiper Control Stalk

Remove the cover surrounding the steering column using a flat-head screwdriver.
Inspect the wiper control stalk for any physical damage or failure.
If damaged, replace the control stalk by disconnecting it from the wiring harness and installing a new one.

4. Test and Replace the Wiper Motor

With the battery still disconnected, locate the wiper motor, usually found beneath the cowl panel.
Disconnect the motor's wiring harness and use a multimeter to test for voltage when the wipers are activated.
- If no voltage is detected: Check the relay and wiring.
- If voltage is present but the motor does not operate: Replace the wiper motor.

5. Reconnect Battery and Test Wipers

Reconnect the 12V battery.
Turn on the ignition and test the wipers to ensure proper operation.
