Relay xxxxxxxxxxxxxxxxxxxxxxxxx If you are referring to a General Motors car there is a recall on the circuit boards for some cars and trucks.
The delay system may not have anything to do with the switch. It depends on the manufacturer but the delay system maybe part of the wiper motor assembly...or the delay is sometimes located in a separate module located separately from the control switch.
where is the wiper switch located on a 85 el camino w/pulse wipers,the car has tilt wheel
It may be due to a broken linkage.
Check linkage first and stripped or loose wiper arm on spindle.
If the rear window is not fully closed the rear wiper will not operate.
a blown fuse.
I'm figuring that this is the same as my 1999 town and country, and I just replaced the wiper switch.. It was easy, and it cost 76.00, and it also had NO effect on the operation of the delay in the wipers. Incidentally, I was trying to fix the delay - What my vehicle does is the delay will work about 4 times, then the wipers "jump" slightly, and the delay no longer works. you have to cycle the wiper switch on and off to get them to go again. Good luck!
Its your linkage, not your motor.
you need to put a new ground on the wiper motor
In my experience it is rarely the wiper motor at fault, it is always a faulty pulse board. Your local auto parts store can sell you an aftermarket pulse board that will outlast the GM original. The pulse board can be easily changed without removing the wiper motor from the vehicle.
The wiper motor is well overdue servicing/replacement. The wiper delay works with the self parking contacts and it sounds that they are fouled/worn out. The slow running would suggest worn motor brushes/motor and gearbox bearings/drive rods and bushes. If you can't service the motor yourself, you should be able to pick one up from a breakers or take to an auto electrician who will refurbish or provide an exchange one
Bad switch? stalk bad wiper motor? bad low speed winding
