I have a 95 toyota camry 2.2L my question is what causes the wiper to keep running even though I turn it off


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.

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.

Rear window wiper starts and runs on its own and dosn't stop until the engine is shut off.


Wiper motors have a circuit which keeps power to the motor until it returns wiper arm to proper rest position even after the switch is turned OFF. Sounds like that circuit has gone bad, replacing entire unit in order.

Wipers wont go off


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.

Rear wiper runs when front wipers are turned on even after it was replaced? Dealer not sure?


The rear wiper on CR-V's is designed to go on when the front wipers are on and either one of 2 things: 1. you turn the rear wiper switch on, or 2. when the front wipers are on, if you shift into reverse, the rear wiper automatically is activated. Is it one of these, or do they just run all the time the front wipers are on? If that's the case, you probably need to have the wiper switch replaced. If the dealer said he's not sure, go to another dealer.
