Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and a flathead screwdriver.
Disconnect the vehicle from the power source by turning off the ignition and ensuring the vehicle is in park.

2. Inspect and Replace the Fuse

Locate the fuse box: Refer to the owner’s manual for the exact location of the wiper fuse.
Remove the fuse: Use a fuse puller or needle-nose pliers to remove the wiper fuse.
Inspect the fuse: Check for a blown fuse (the wire inside should be intact).
Replace if necessary: If the fuse is blown, replace it with a fuse of the same amperage rating.

3. Check the Wiper Control Stalk

Remove the steering column cover: Using a flathead screwdriver, carefully pry apart the cover to access the control stalk.
Inspect for damage: Look for any broken wires or obstructions that may prevent the stalk from functioning.
Reconnect or replace: If any issues are found, repair or replace the control stalk as necessary.

4. Test the Wiper Motor

Access the wiper motor: Remove the cowl panel to gain access to the wiper motor.
Check electrical connections: Use a multimeter to test for voltage at the motor connector.
Replace the motor if non-functional: If no voltage is detected and the fuse is intact, replace the wiper motor.

5. Check Wiper Fluid Pump

Inspect fluid reservoir and pump: Ensure that the wiper fluid reservoir is filled.
Test pump operation: Activate the wiper fluid spray function and listen for the pump. If silent, check connections and replace if necessary.
