Wipers keep running wont shut off - Cars & Trucks

Try replacing the switch that turns the wipers on and off, The switch may be worn/broken and stuck in the on position.

Sounds like the switch is broken, so you can never turn wipers off, or when you shut ignition off, do wipers then shut off? Need to have more input to diagnose. Switches are usually culprit.

-possibly relay stuck in "ON" position. Unplug the relay and plug back to position. If it still on then replace new relay.


Good Luck

sound like the window wiper stalk has a short in it causeing the circuit to remain constantly on so might need to be replaced that would be the first thisng i would do then go further chcking wiring and fusines

There is a device made into the wiper motor itself, known as the wiper park switch. Its designed to turn off the wipers at a pre-determined position once you switch them off. The mfr recommends replacing the motor along with the intermittent timer (if equipped) at the same time when experiencing these problems.

hi check the wiper relay in the fuse box under the bonnet it might be stuck in one position and keeping the wipers on all the time..hope that helps to start with

When you turn off the switch, there is a second switch in the wiper motor that continues to run the wipers until they are parked. If the window where that switch does not keep the wipers running is too narrow, the momentum of the motor turning will carry the wipers past the end of that window—they will continue until they are not-quite-parked. But not-quite-parked, in an absolute sense, is not parked at all, and that switch will reestablish contact, running the wipers to try to get them to the parked position.

Once there, the overrun happens again, and the cycle repeats.

Beyond that, if that switch gets stuck it will keep running the wipers, parked or not.

Sometimes the wiper motor can be easily accessed, opened up, and that switch can be serviced and properly adjusted. Sometimes the motor needs to be replaced.

Find the connector that runs the wipers, and disconnect it while the wipers are running. The blades will stop where they are.

intermittently, and briefly, reconnect the wipers trying to get them to move only 5 or 10 degrees at a time. This will avoid the motor get up a head of steam. If the wipers stop responding to this once they are parked, the window that the switch considers "parked" is too narrow. If they just keep responding to the application of power, even when they are really in the parked condition, then the switch has arced shut.

small plastic cam in colum atached to switch . stick a screwdriver in thier and flip it the oly way it will go. or u could just replace the switch. u might just have a short to. do they keep running with the car off

Check to make sure you are getting power to the wiper motors. Also check relay. Either one could be bad.

The routine (resistor) that shuts off the wipers and parks them correctly is in the wiper motor, not the switch. I assume your switch is good since you make no complaints about its movement. One thing to check before replacing wiper motor is to loosen the wiper arms, and let the motor park itself in what you feel is the bottom of windshield position. Now align the wipers and retighten.

If these get positioned wrong after, say, a frozen morning, this will affect parking of wipers since motor "park" is no longer in synch with wiper arm "park."

Otherwise, if wiring and positioning are correct, I recommend replacing the wiper motor itself.
