Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the ignition off.
Disconnect the battery to prevent electrical shorts.

2. Check and Replace Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the wiper fuse using the diagram on the fuse box cover.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse; if it is blown (the filament will be broken), replace it with a new fuse of the same amperage.

3. Inspect and Replace Relay

Locate the wiper relay in the fuse box.
Remove the relay by pulling it straight out.
Swap it with a similar relay (if available) to test if the wipers operate normally.
If the problem resolves, replace the faulty relay with a new one.

4. Check Wiper Control Stalk

If the issue persists, remove the steering column cover to access the wiper control stalk.
Disconnect the wiring harness from the stalk and check for continuity with a multimeter.
Replace the wiper control stalk if it is found to be defective.

5. Inspect Wiper Motor and Wiring

If the stalk is functioning correctly, check the wiper motor connections.
Ensure all harnesses are securely connected and inspect for any frayed wires.
If faulty, remove the wiper motor from its mounting (usually requires a socket set) and replace with a new motor.
