1991 grand marquis wipers park?

[Sign of the Cat]

Hope someone can help me, my friend has a 91 grand marquis and when you turn the wipers off they go down to park but then the gor back all the way yp and park there... I had an 86 at one time with the same prob and all it was...was a simple ground... not this one...hope some one can offer me a suggestion...thanks

try a new wiper motor...it may be the only option...but I have a similar problem and it didn't help...it's prolly something electrical

[Nathan in MI]

I doubt the motor is the problem...if it was the wipers probably wouldn't work at all. My money's on the wiper control module.

ya, isent there a intermitent wipper controle module? that might be the prob

There is a parking cam inside the wiper motor assembly that tends to wear out. Unfortunately its not replaceable by itself mostly because the parts are not available anymore.

Colin was also suspecting his control module last I heard. The wiper wiring is straightforward but hard to locate under the stock dash. I showed him the attached picture I took with the dash out - maybe it could help you too.

The plug from the wiper/washer switch (1) and the big grey plug that goes to the wiper motor (2) both lead to the little black box thingie (3). Of course, this is with the dash out; getting to it from underneath will be more fun.

Your dash scares me very much. Wire nuts and crimp connectors :hairraise:

Actually, some of that is experimental just to make sure I could get things working. I'll probably be neatening it up a bit within a few months.

My mother's '94 Vic had the same problem. Turns out it was the motor. They would go up and stay there. But, if you caught it at the right time, you could push the wipers down. The motor still works right? I am not sure but it may have been noisy when operating it. Good luck I hope you can find what the problem is.

to come and think about it, my bros 89LSC had that prob too, was the motor.

[Blaze86Vic]

Usually it's the motors. Mine does some funny shit, and I know it's the motors because my module, and lever are brand new old stock.

gonna try the motor once i get a chance to pick one up.will let everyone know how i make out

[Dave84]

cool hopefuly that fixes it

[86VickyLX]

Good luck. Make sure it's a remanufactored one. We got a junkyard motor and it had the same problem. Not that I am saying they are all bad. It's worth a try. Can't diss the u-pull-its! My hero!!!!!
