How come my front windshield wipers wont work

Check to see if there is power to the wiper motor. The motor may be bad or there may not be power to it.

The wipers worked for a second they crossed over each other then they quit working. Now they go up about 6 inches but they won`t go any further. I thought they might be bent but that's not the problem.

Hi,

The wiper linkage came apart. To access it, you need to remove the cowl at the bottom of the windshield (outside). If you open the hood, you will see the screws holding it on. Also, you will need to remove the wiper blades/arms.

Let me know if you have any other questions.

The wipers on my car stopped working. It is working only with washer fluid button, but when I turn on wipers they donâ??t work. Could you help me figure out what the problem may be? Thank You!

check wiper motor.

might be the wiper switch if they are working when you wash the window with the washer fluid.

how can I obtain and electrical schematic of the on board computer and also the pin layout to be able to trace the circuits of the lights and wippers which dont work

Welcome to the world of complicated, unreliable, unnecessary computers. First check all the fuses under the hood and under the dash behind the brake pedal. The fuses by the brake pedal are notorious for falling out onto your ankle. The lights and wipers are run by the Body Control Module, a computer. It is tucked up against the firewall, plugged into that fuse box by the brake pedal. Once it is removed, there is no way to troubleshoot it while powered up.

Inoperative wipers is a common failure in the computer, but often they will run for three cycles when you press the washer button. Some people run a switch from the wiper relay to make them work in one speed rather than replace the computer. First, check fuse number 9, a 30 amp under the hood in the Power Distribution Center.

Which lights do not work? Fuse number 6, a 40 amp under the hood runs the parking lamp relay, and fuse number 19, a 20 amp, runs the signal flasher. Inside, in the junction block, fuses number 1, 4, and 12 involve computer-controlled outside lights. The only lights that don't involve a computer are the license lamp and the center high-mounted brake lamps. The body computer runs the headlamps through low and high-beam relays and four separate fuses, and it is not likely all four fuses are blown.

The instrument cluster illumination lights are computer-controlled, but the fuse shown in the diagram is turned off with the ignition switch so it cannot be the lamps fuse. It would appear those lamps run off the same fuse as the wiper switch.

Before you tear into the body computer, recheck all the fuses inside and under the hood. If fuse number 9 is blown, suspect a shorted wiper motor. One of the contacts overheats and melts into the plastic gear it rides against. The next time you turn it on, the contact bends and is pushed up where it shorts against the metal cover plate, blowing the fuse.

If the lights you are referring to are the instrument cluster lights not coming to life when you turn on the ignition switch, suspect a defective ignition switch. The contacts overheat and melt into the plastic, or the connector melts from overheated terminals. The circuit usually affected is for part of the instrument cluster, power windows, wipers, and the radio. This is more common when the heater fan is used in "high" very often.

my wife drives a 97 caravan and the windsheild wippers stoped working, a had a mechanic try to trouble shoot the issue and they came to the conclusion that it is a bad BCM. they checked the wipper motor, interior switch with no results. when i push the interior switch for the wippers to wet the windsheild the wippers will come on but only for 5-10 seconds and then stop. any ideas???thanks

Hi, if you just turn on the wiper, no wash, do the wipers work okay? I cannot be sure about your make and model, but on some, when you hit the washer, the wiper will only work for a few seconds, then shut off.

i am sorry i should have explained it a little better, the wipers do not work at all when you turn them on, they only work with the wash feature?

I see, check fuse nine 30 amp, underhood fuse box, use testlite should be hot all the time. Also, check the high/low wiper relay, under hood fuse box. Pull the relay, turn on wiper control, use a testlight, terminal 30 and 87 should be hot.

My two cents worth: The Body Computer is a very common problem for exactly the symptom described. Thank you for the observation about the washer causing the wipers to run for a few swipes. That's the clue that clinches it, and it proves the wiper motor and wiring are okay.

Unfortunately, replacing the body computer is not a do-it-yourself procedure. It is even frustrating for the professionals. The module is plugged in next to the firewall in front of the brake pedal, and some bolts must be removed to get it out. Too bad the engineers saw fit to complicate a simple, reliable circuit with an unnecessary, expensive computer. The wipers in my 1988 Grand Caravan do exactly the same thing with a switch and very inexpensive module.

After a few minutes the wipers quit working. I have been told I need to check the ground. How do I do that?

You need a test light or volts meter for the test. check fuses if all okay check for power at the connector if you have power I would say you need a new wiper motor.

my windsheid wipers will not work, I checked the fuse, I bought a used motor at a junk yard, it worked for a couple of days, now will not work again, could there be a problem with the connection maybe dirty or greasy , let me know Thanks

check for a bad ground. run a test ground wire to the motor first suspect a bad motor.

I was driving in the rain the other day and my windshield wipers stopped mid swipe and won't come back on. We checked the fuse and it is fine and we can hear the wiper motor running but nothing happens as a result. What might be the cause and how do we fix it?

Since both wiper arms stopped, and you can hear the motor run, it sounds like the linkage is disconnected at a ball and socket joint. You will find that you can move one arm and both will move together.

When only one arm stops moving, it is usually a loose 15 mm nut on the arm pivot. Just lift the plastic cover at the base of the arm. It will snap up revealing the nut that must be tightened.

Less common is a pressed-on linkage arm that falls off the pivot. The assembly must be removed for this repair. The arm is tapped back onto the splined shaft, then a light tack weld will prevent it from coming off again. This will also cause only one arm to stop moving, and moving one arm will not cause the other one to move.

My daughters was out in the snow and her wipers stopped, they work fine and then stoped. I m from older school of glass fuses hers are a plastic prong looking fuse how do you know if its the fuse or the motor? and if its a motor could you tell me where it is on this car and I might be able to do the work I hope. Her husband works two jobs and she needs to have this car running with 3 kids any help you could offer a grandma gal would be helpful... thanks so much Laurie

Best way is with a test light. It can be bought at the store here. The details on testing fuses is here also. Make sure it is not just a bad wiper motor ground. Use a jumper wire. run it from any good engine ground to the motor case to check it. OKay if you need any help, just e-mail me. The outer cowl must come off, and both arms.

the windshield wipers will not work. I can here the motor and it sounds like it is moving at the correct speed for the speed I put them on, but the wipers themselves do not move. Any suggestions on what might be the problem, and could I fix this problem myself easily at home?

thanks!

get a new wiper motor but do not turn the core in, put the new motor on, and if problem is not fixed return the new motor and check for wiring problems, the reason you do not want to turn the core charge in (your old motor) is that the next day or so they turn the old motor in and have them rebuild it, if possible got to advance auto parts and get a motor built by GP Sorensen.

When I got the van sometimes when you hit the turn signal for a right turn the wipers would come on.
But now they will only work in the lower intermediate range, but just barely. The washer part works just fine, hit the washer and they come on. The rear one works fine.

We checked the fuse and the relay( we did change the relays) and they seem to be fine. My mechanic replaced the switch on the column, but that was not the problem, so he replaced the wiper module, still the same problem. So we are stuck without wipers. What else could cause the wipers to not work. Also is there a plug in where if I took it to say advance auto for them plug it into a diagonostic.

No computer readouts for the wipers. Check to make sure there is twelve volts of power to the motor. The motor itself may be bad.
