Understanding the Problem:
* Stuck Wiper Motor: The most likely culprit is a malfunctioning wiper motor. It could be jammed, overheated, or have a faulty internal switch that's keeping the motor running.
* Faulty Wiper Switch: There's also a chance that the switch on your steering column is stuck in the "on" position.
* Electrical Issues: A short circuit in the wiring to the wiper motor or switch could be causing the problem.
Troubleshooting Steps:
1. Check the Wiper Switch:
- Turn the ignition key to the "ON" position, but don't start the car.
- Carefully move the wiper switch lever through all its positions (off, intermittent, high speed).
- If you can feel any resistance or hear a clicking sound when moving the switch, it might be stuck.
2. Check the Wiper Motor:
- With the engine off, check the wiper motor for any signs of overheating or unusual sounds. It should be cool to the touch.
- If the wiper motor is running continuously, try disconnecting the electrical connector to the motor (this will stop it) and then reconnect it. See if that resets the motor.
3. Inspect the Wiper Fuse:
- Open your fuse box (usually located in the engine compartment or under the dashboard).
- Locate the fuse for the windshield wipers (consult your owner's manual).
- Carefully remove the fuse and inspect it. If it's blown, replace it with a new fuse of the same amperage.
4. Check for Wiring Problems:
- If the fuse is fine and the motor still runs continuously, there might be a short circuit in the wiring.
- Look for any damaged or frayed wires running to the wiper motor and switch.
- You can also use a multimeter to test the wiring for continuity and voltage.
Important Notes:
* Safety: Always disconnect the battery before working on any electrical components.
* Professional Assistance: If you're not comfortable working on your vehicle's electrical system, it's best to seek professional help from a mechanic.
* Troubleshooting Tips: It's helpful to have a friend assist you while troubleshooting, one person to manipulate the switch and the other to observe the wiper motor.
