Windshield wipers do not work

Six cylinder two wheel drive automatic 98,000 miles

Help! This is what i have done so far and what is going on. I had a problem first with the instrument panel going out. i changed panel and nothing then changed BCM and bingo working panel, but now wipers do not work. i checked all fuses there okay. checked relays there okay. no power to the wiper motor, ran a hot wire to check anyway and it is okay works. checked power to switch and plenty. checked ohms coming from BCM. It was able to jump the switch to work the hi/low relay,but not wipers. Where do i go from here? do i change the whole turn/wiper/wash flasher switch on the column? or am i looking for something else? oh, and i also checked grounds, cleaned battery terminals, and fully charged battery. thanks in advance.

If fuse 19, your "wiper on" and "hi/lo" relays are good, it has to be the switch. The wipers should work on high/low even it the delay function in the multi-function switch is bad. You are losing power somewhere it could be the BCM let's find out for sure by following this guide and the wiper wiring diagrams below.

Check out the diagrams (Below). Please let us know what you find. We are interested to see what it is.

thanks. i hope we are right. $100.00 switch. i will let you know if it works. :-)

Before you go out and spend that $100.00 make darn sure the "wiper on" and "high/low" relays are good.

allready checked them both work fine.

Okay, sounds like you know what you are doing. Just wanted to make sure. Let me know what shakes.

yes, i definately will. i am searching online now for the switch hoping to get a better deal then the local parts place. :-) yes, i am an older vech mechanic learning this new computer stuff. i just wanted to make sure that i cross all the t's and dotted all the i's.

I would not be afraid of used if you can find one. They are easy to replace

Hello,

I need help trying to figure out what needs to be replaced before I dish out too much money. Yesterday my front windshield wipers blades worked in the morning. Later that day I gave a jump start to a friend, closed the hood and it started to rain. I tried to turn on the wipers and it was making the noise like it was trying but the blades would not move. I had to physically move blades to clear window to drive. It says I am out of windshield washer fluid and it still makes sound like it is. So, we checked the fuses, they were all good, replaced it just in case anyways. Still, the blades wont move when I turn them on. Please help!

i was thinking the same thing my only concern would be if i bought a used one and it still did not work i would be wonder whether or not the new used switch was bad or still have another problem. as to where a new switch i know if it works great and if not i got a major problem some where else. I have been reading the post's on the Voyager and I am seeing lots of unsolved problems with the wipers, instrument clusters and so on.

Welcome to the forum, If the wiper motor is not working, I would check voltage at the wiper motor. Red wire with yellow tracer is voltage for high speed, use a test light to check for voltage. Brown wire with white tracer is voltage for low speed. Check either one or both for voltage. Take electrical connector loose from wiper motor, turn the key on, you should not have to start it, turn wiper setting to low, use test light on wire already mentioned. If no voltage, fuse five 20 amp in fuse box, should be for wiper. Other possibilities, wiper linkage is hung-up, wiper motor is faulty, My information did show a 9 amp circuit breaker on ground side of wiper motor, not sure if that is replaceable or part of motor?

We get a "lot" of posts for Voyager and Caravan electrical problems. I think the only that is worse is Saturn. On the Chrysler products it is mostly ignition and lighting.

okay, got the new wiper switch. Still not working. where to next?

I have not forgotten about you. I am having problems with my resource program and hope to have it back up yet today. As soon as I get it back, I will get back to you.

It seems strange that the wipers quit "after" you changed the BCM. Was the BCM new or used? Do you have a wiring diagram for the wiper/washer system? If not, if you have, or have access to, a fax number I can ship you one. I can attach it to this post but they do not through very clearly. If the relays and fuses are good, and the switch is new, The only thing left is the BCM. Let me know.

After turning on the wipers, they will swipe four or five times then quit. If I hold in the washer button, they will keep running as long as I hold in the button but quit again when releasing the washer button. Any suggestions?

Okay replaced BCM again, the wipers and everything worked great for about a week. now lights and horn are flashing like i have an alarm system and it will not start. (no alarm system) turn key on lights and horn flash, but no start. all electrical stuff work.

Body computer. The insane engineers can no longer make a simple wiper motor work with complicating the circuit with an unnecessary computer. The result is lots of expensive failures and repair bills. You might want to plug in a multi function switch from a salvage yard first to be sure it is not the cause, but suspect the body computer.

my vehicle has 140,000 miles and has a 3.3L. A couple of days ago, the right windshield wiper stopped working. I removed it, and I saw that the little bolt that comes out of the wiper motor was worn off. Do I have to replace the whole motor, or can I just replace the bolt and the windshield wiper arm? Thanks for your help.

if the second wiper works, then motor is okay. change the bolt first and see if wiper arm will work, if not, change the wiper arm as the threading may have worn.

hi, all of a sudden when i started my van my windshield wipers and my turn signals are not working and the air bag light is on. I checked fuses all good. please help it is raining.

Hi tammydovo. Welcome to the forum. Be sure to check the fuses in two places, under the steering column and under the hood near the left rear corner. Physically remove the fuses under the hood and look at them. It is not uncommon for the air bag fuse in the upper corner of the box to corrode. It will also affect the radio.

If the fuses are okay, suspect a burned contact inside the ignition switch or overheated terminals and wiring in the ignition switch connector. If contacts inside the switch are the problem, wiggling it or turning it on multiple times might get it working again for a little while.

My windshield wipers are not working properly.
Sometimes they will not shut off even when the keys are out of the vehicle. The delay function is wacky, sometimes the wipers stop in the middle of the window. You never know what will happen when you use the wipers, but the biggest issue is when you turn the off, pull out the keys and they keep running. You never know when they will decide to stop.

welcome to the forum. There is a wiper on relay in the power distribution center, under the hood. Voltage to the coil and load side of relay, is hot all the time. The BCM grounds the coil side of relay in order to energize. The wiper switch sends a signal to the BCM , the BCM grounds the coil side of wiper on relay. The problem could be almost anywhere, relay wiper switch BCM or wiring circuit. You might have the codes checked, see if it points to anything?

what is a "BCM " ?

Hi, BCM is body control module.
