Solution

1. Preparation

Gather necessary tools (see Tools Required below).
Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace Fuse

Locate the fuse box (usually under the dashboard or in the engine bay).
Identify the wiper fuse using the fuse diagram.
Remove the fuse and inspect it for continuity.
- If blown: Replace with a fuse of the same amperage (typically 10A).

3. Inspect and Repair Wiper Control Stalk

Remove the steering column cover using a screwdriver.
Disconnect the wiper control stalk connector.
Inspect for damage; if damaged, replace with a new stalk:
- Disconnect the battery before replacing.
- Reconnect the new stalk and reassemble the steering column cover.

4. Test and Replace Wiper Motor

Locate the wiper motor (usually under the cowl panel).
Disconnect the power connector from the wiper motor.
Using a power source (like a jumper wire), connect directly to the motor:
- If the motor operates, replace the motor.
- If it does not, further inspect wiring or replace as necessary.

5. Inspect Wiring and Connectors

Visually inspect the wiring harness leading to the wiper motor for damage.
Clean any corrosion found on connectors with electrical contact cleaner.
Repair or replace any damaged wiring as needed.
