Broken windshield wiper controls: The switch that you use to turn on the wiper motor is put through a lot of use and may eventually malfunction inside, causing the wiper motor to run continually no matter what setting you choose.
Park switch malfunction: The wiper motor contains the park switch. When the windshield wiper system is turned off, an electric current will still flow through it if this switch malfunctions. If the park switch is the source of your issue, your wipers may even keep operating long after you turn off your car, draining your battery.
Bad wiring: Your windshield wipers may continue to operate even after being turned off due to a weak wire or faulty connection. A mechanic with the right diagnostic equipment can quickly inspect the wiring and find any problems.

Where is the switch for the windshield wipers?
The switch for your windshield wipers is inside your automobile and is fastened to the steering wheel. The wiper motor activates or deactivates the wipers when the driver flips the wiper control. If the wiper blades won’t stop, the problem could be with the motor rather than the switch or with the “park switch.”
Why do my windshield wipers turn on as soon as my car starts?
I’m sorry to hear that, but that sounds like it may be very frustrating.
Your windshield wipers are there when you need them, just like auto insurance, but what happens when they break down? The most frequent causes of automatic windshield wiper activation are listed below.
- Park switch issue: The windshield wiper motor houses the park switch. The wiper system will still be receiving electricity if it is malfunctioning. If the wipers continue to operate while your car is off, this can drain your battery!
- Broken controls: Because your car’s windshield wiper switch is frequently used, it may develop an internal defect that keeps the wipers on regardless of the setting you select.

Do windshield wipers shut off with the automobile when it stops?
One of the devices in your car that you should turn off to prevent draining the battery is the windshield wipers. By parking our automobiles inside a garage or another facility with greater temperature control during the summer and winter, we may avoid battery drain.

They can probably test your battery and identify any issues if you have AAA or visit an auto parts store. Once you’ve confirmed that your battery is in good working order, you can resume driving.
A wiper park switch is what?
In contemporary vehicles, a control module manages the wiper motor. It may be referred to as the front BCM or the Body Control Module (BCM) (FBCM). Multiplex Integrated Control System MICU is how Honda refers to it.
As shown in the diagram, the control module is controlled by the multifunction wiper switch on the steering column, and the wiper motor is operated by the control module via wiper motor relays.
There may be up to three relays: one for the high-speed circuit for the wiper motor, one for the low-speed circuit, and one for the circuit for intermittent wipers. Not all cars use the same diagram. If you require the correct schematic for your vehicle, you can acquire a factory repair manual by subscribing to one of the links we provided at the bottom of this post.
In order to check the multifunction switch’s functionality when diagnosing a wipers issue, mechanics at a dealership can access the control module with a scan tool.
A scan tool also permits an active test, which entails activating the wiper motor from the scan tool.
A set of gears and a park switch are part of the 12V DC (direct current) wiper motor. When the wipers are in the “park” position at the bottom of the windshield, the park switch enables the motor to shut down.
