Car Forum / Dodge / Dodge Cars / September 2005Windshield wiper malfunction
My '97 Dodge Caravan has an annoying problem where the wipers will activate once in awhile on their own. I've tried messing with the turn signal indicator and knob that usually turns on the wipers looking for evidence of a bad contact without luck. I cannot duplicate this problem on my own, but it appears from time to time. Does anyone have this same problem? What did you do to fix it? Thanks in advance. Mine does the same thing. Maybe 1,2,3 swipes. May do it 2 days in a row, then it may behave it's self for 6 months. It's always a suprise, but at 135000 miles I'm not going to worry about it. > My '97 Dodge Caravan has an annoying problem where the wipers will activate > once in awhile on their own.

That has been a problem for yrs, we call it the phantom wiper or its a device built into the windshield called a pollen sensor and when pollen is detected it wipes one time,,,no serious now... if they turn on when the car first starts it may be an indication of a low charge in the battery, other wise, replace the multifunction switch, its very easy to do, just need a philips screwdriver glenn beasley chrysler tech > My '97 Dodge Caravan has an annoying problem where the wipers will activate > once in awhile on their own.

There is a TSB on this problem...the TSB has been out for 5-6 years. Had my 97 GC fixed back in 98-99 by the dealer for no cost. Call your local Dodge/Chrysler dealer...they may need to do some research on this "old" TSB at this point...but be persistent. | Our 96 van has done this since it was new.

Notice the lubricant grease around the edges that is still clean. scrape it of with a screwdriver and set it aside to use later. Only the clean grease. Now clean the contacts used for the wiper with a papertowel and a solvent (carb cleaner is good, no residue). Use some very fine sand paper, 600 or 800 and clean the contacts enough to get the corrosion off and clean up the contact wear areas. put the clean grease back on and button it up. You'll see that this solves the problem for a few years. Explanation: I suspect small metal particles are allowing some conduction twixt the contacts that the computer is interpreting as a need to run the wiper. I decided to do this after reading that the TSB was simply replacing the switch with an identical switch. worked for me. > Thanks for the insights.

Sometimes nothing happens for days but then suddenly the wipers start functioning. Also my Internal Dome lights dont work when I open the door or press the switch. The Fuel guage also behaves spooky many times. It shows anywhere from full to half. I have to check the miles after every few days to fill gas. Showed it to the mechanic, but he said the computer need programming. This reprogramming will reset the odometer also which I am bit afraid of. Also this will cost around $500 w/o labour. Can anyone help me with my Spooky-Van ? > The TSB is old but it simply has you replacing the switch unit. > [quoted text clipped - 56 lines] >>> | > > >>> | > > Thanks in advance. There is no program for none of that, and there is no way to set the odometer by reflashing a controller. The fuel gauge problem is more then likely a bad worn out fuel sending unit in the tank., As far as the wipers go, it could be anything from The BCM body control module to the wiper motor to the wiper circuit, Check fuses for the dome lamp circuit??? And find another mechanic, sounds to me like he dont know what is going on Glenn Beasley Chrysler Tech > I still have this wiper problem after changing the switch.

I will change the mechanic. Will is be good to take to the Dodge dealer for such things since its a 98 Dodge ? > There is no program for none of that, and there is no way to set the > odometer by reflashing a controller.

Any technician that is familar with the BCM/wiper system, But we at the dealer have the shop manuals that Chrysler printed and all the uddates for the manuals and the technicians that have been working on these cars day in and day out probably have a better chance of diagnoising the system more effectively, Im not in any way trying to bad mouth the independents, this is just my opinion > Thanks Glenn.

As you probably know by now, this has been an ongoing problem with the Caravans, I have found the problem to be a faulty RELAY switch located under the hood in the BLACK fuse box panel. The RELAY location is (from the left, the third one to the right) for the WIPER on /off. The part looks like a 1"square block that simply plugs in. This is also the same type RELAY that is used for the wiper PULSE, which could also cause the problem, but not as likely, anyway they are interchangeable so you only need to buy one---J |
