A bad relay switch will cause the windshield wipers to not turn off. Replace the relay switch and the windshield wipers should turn off.
My problem is that when I shut off van my lights come on and window wipers also... no radio, heater is always on high... which relay switch controls all these?
It controls the intermittent wipers
the relay is in the tail gate as it also controls the rear screen wipers
The windshield wiper relay switch can be found on the firewall in the engine compartment. The windshield wiper relay switch will be on the passenger side of the firewall.
The windshield wiper relay switch can be found in the engine compartment on the firewall. The relay switch will be next to the windshield wiper motor.
I believe it s a relay
The wiper switch on the ParkAvenue could be bad. Or, the intermittent relay for the wipers could be stuck, causing the wipers to run.
Function that it controls won't work, but fuse and switch are good
The relay that controls the rear windshield wipers is typically called the "rear wiper relay." It is part of the vehicle's electrical system and is responsible for supplying power to the rear wiper motor when the rear wiper switch is activated. In some vehicles, this function may be integrated into the body control module (BCM) rather than a separate relay. Always consult the vehicle's owner's manual or service guide for specific details regarding the relay location and function.
It has to be the switch. It is what controls the power to the wiper motor. If the switch is fried again I would check that the relay (or that the fuse is the right amperage) has been fried in the open position somehow. This would allow unchecked voltage to fry its way through your switch to power the motor. I hope this helps you some.
You either have a bad relay, wiper motor, or bad switch.
