Try adding a ground wire, just take a wire and rub it on the motor ad the other end to ground on battery. i find alot off problems are caused by bad body grounds or on gm wiper motors the internal ground goes bad. grounds are one of the biggest problems in electrical systems on all trucks and cars.

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.

Wipers keep running wont shut off


Electrical control to the wiper motor are also stuck in "on". It could be the switch, or the relay for power to the wiper motor or a short somewhere to a positive source of power. You should be able to remove the wire connection to the wiper motor, but protect it from shorting on any body metal (ground) or negative. by with tape on the end. Until you get the problem sorted out.

Wiper oes not shut off why?


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


Good Luck

Wipers won't turn off


The wiper motor is defective and needs to be replaced. Inside the wiper motor is a "Park Switch". When you turn the wipers off, the park switch sends a signal to shut the wipers off. If the park switch fails to operate then the wipers will continue to run, unless the ignition key is turned off. You will also need to inspect and test the charging system. Where you had no issue before the rain, you may only need to charge the battery. After the battery is charged it should be load tested, to be sure that it is fine. Also test the alternator and make sure that it is charging correctly (@14volts). If you need more information please write back. Good luck.

Wipers don't stop why


the wiper motors have a sustain function inside
this magic switch, keeps wiper going it driver kill it with the switch.
preventing mid windows, stops. (safety and vision issues)
so that switch can break, and do what you said.
ive actually rebuilt them. and fixed the switch, many look mangled .
its inside the motor cover , below the wires connected there.

fix it, or replace it.

or the start up wire is hot all time.
the start up wire is the switch wire.
you turn off the wiper switch and its output goes to 0v, that be good
if stuck at 12v, its bad.

one way to check that is pull the switch connector (combo)
does wiper stop, yes, bad wiper switch
no,then bad wiper motor guts.

Windshield wiper washer switch , the fuse keeps blowing 20a it goes about 5 times and then blows the fuse i put a 30a fuse in and it bypasses and it wont switch off / on


Do not put a larger amperage fuse in. you run the risk of the wiring over heating and starting an electrical fire. More than likely the wiper motor is starting to go bad and is drawing an unusually large amount of current which causes the fuse to blow. Replace the wiper motor.

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 do not work Sometimes


Hello, This is usually one of two problems.

1. The wiper motor has gotten weak or a dead spot in the motor windings. this would cause it to not start depending on where the motor stopped last. The motor is usually a easy change.

2. The other things it could be is you wiper switch has a bad connection or just in need of replacement. This could be a harder job depending on how much of the column you need to take apart to get the lever switch out.

I would lean toward number 1 its usually the more common problem. I hope my answer at least gets you in the right direction. I hope you have a great weekend:>)

Windshield wipers wont shut off


The problem is in the wiper motor assembly. Did you ever notice that when you switch the wipers off they always go back to the home position? This is due to a switch that keeps the wiper motor operating until the wipers are parked. In many older GM vehicles this is accomplished with a leaf type switch which opens when the wipers are in the correct position. when the dash switch is turned on this switched is bypassed keeping them on-when the wipers are turned off the motor continues to operate until this connection is broken.

Inside the wiper motor housing there is a nylon gear that drives a cam that cycles the leaf switch-most likely the gear has become damaged so it no longer drives the leaf switch allowing the switch to remain closed. A cheap fix is to disassemble the motor unit and piece of tape between the contacts. Although the wiper will not park properly they once again can be controlled by the dashboard switch.

In later vehicles the wiper position is located with an electronic sensor with a small PB board - the repair of this gizmo is beyond the scope of most shade tree mecahnics - so the solution is to replace the entire wiper motor assembly - unfortuneatly.
