Try Replacing the relays, that'd be my next bet
A.J.,Try Replacing the relays, that'd be my next bet
Chrysler TSB 08-31-98 addresses this and there are 3 possible conditions with the cure for one condition being to replace the MFS which you did. The other possible condition has to do with grounding so be sure to check the ground by the transmission dipstick (i.e tighten the nut if loose and check for a broke wire). You should have a good solid ground to pin #5 of the gray connector attached to the bottom of the PDC. There should be continuity between that pin#5 of the gray connector on the PDC to the center terminal of the windshield wiper "ON" relay (per the TSB).A.J.,
I just swapped them both out and it works the same as it did before--GHOST WIPING>>>>
Thanks for the info!

The final procedure involves a few continuity tests between the BCM and the wiper module
(I could post these if you would like me to tomorrow. In the mean time, you may be able to locate the TSB online or from someone who has it electronically). Essentially the final procedure either involves correcting an open wire or replacing the wiper motor.
As I recall from previous posts on this subject, it is possible to open the motor and clean the park switch. Perhaps someone has a good description of the procedure. My first guess would be the park switch in the motor assembly. You might be able to pick up a junk yard motor fairly cheap and then try to rehab your motor for future use.
The bottom of the power distribution center under the hood (PDC) has several connectors plugged on the bottom and I believe they are all a different color. I'll check the factory manual to see if there is a wiper "on" relay and where it is located. I probably can do this tonight but can't make any promises. PM me with your E-Mail and I might be able to scan a pertinent info on to a file and send it. Again, will do on a best effort basis.I checked the ground next to the tranny, cleaned it up well and reconnected it. Same results. Replaced the wiper motor. Same results.
Can you be more specific concerning the TSB as it relates to pin #5 of the gray connector on the PDC to the center terminal of the windshield wiper "ON" relay (per the TSB).
Thanks,
Good post and good information. Interestingly enough, I haven't had the ghost problem yet on my 96, but I did have a bad relay the caused the wipers to keep running after after you turned the switch off. The relay contacts would stick together and there was no way to shut the wipers off except pull the relay.Over the years I have addressed this problem on my van at least twice. The ghost wiper problem causes the wipers to swipe when they are not on and sometimes to continue to run after they are turned off. They will swipe a few times and then stop in the middle of the windshield, until you turn them all the way on and then you have to time it right to get them to stop where they are supposed to. I did not replace the switch or the motor, in fact I didn't replace anything. I know some folks have had success replacing the switch or motor, but I know what worked for me. The simplest way I can describe the problem is that the wipers don't know when (or perhaps where) to 'park'. There is a small plastic part in the wiper assembly, somewhat circular, that has small metal fingers in it. It rotates inside as the wipers swipe and senses, with the metal fingers, when the bottom of the cycle is and to 'park'. This part needs cleaned and perhaps the fingers bent slightly to make a good connection again. This is not a difficult job, but it will take a couple of hours to do. You have to start at the wiper arms and remove the whole wiper assembly. Then work your way down to the 'park' sensor. (probably not its proper name) I was able to take mine apart and clean it and reassemble the whole thing. I worked perfectly for about 5 years and I cleaned it again and it worked perfectly again, that was probably 4-5 years ago. I would expect it would need it again soon, but the van is on injured reserve right now with a bad transmission until I can decide what to do about it. 215000 miles on the original transmission, so I'm not complaining. There ussed to be some detailed posts on here that led me to do this repair, but that to was many years ago. Hope this helps.
