the other day as im leaving the lika store my wipers turn on by themselves and then stop halfway. then i try to shut them off and the only position that works is full speed but they still wont go all the way down. then later in the afternoon, my headlights startedd turning on and off very irradically. and still later my windshield washers stuck on for a while and i couldnt see **** as my wipers were not going.
i called the dealership to make an appoinment and the first thing he asked me was if i had an aftermarket alarm installed. there was one in the car when i bought it and i have no idea what it does. i think theres a remote start i just havent taking the time to try to figure it out yet.
any help would be appreciated

No, and I just installed an aftermarket remote start / security system. All is well.

I had this exact problem with a brand new CVPI 2002. Dealer replaced the wiper motor under warrenty.

If you are having problems with both headlights and wipers it is most likely the multifunction switch (turnsignal,highbeam,wiper switch). Sometimes you can clear up the problem temporarily by banging on the washer part of it. Make sure the dealer or whoever checks the condition of the connectors to it, too. These can become overheated and cause weird things.

BigDog had a variation of the problem.
I think it took a few dealer visits to finally solve his problem.

Tonight in the rain my wipers stopped working. They worked intermittently and then stopped altogether, but DO work on high speed only. Last week my air bag light came on. The wipers have never come on by themselves. They also stay up and won't reset.

18 months ago I _did_ have a Viper alarm w/ remote start installed. Why would the dealer ask about the alarm? Is there a connection between the alarm and the wipers not functioning, or the air bag light? Is he going to try and screw me because I had the alarm installed? (Of course how would you guys know that...).

Thanks for any info. I need to get under the seat and check the air bag connections as well. Right now it flashes 1-9 1-9 1-9 and then stays steady.

There is enough similarity between your reports and mine on the wiper function on high speed only, and we both have an alarm, so maybe the dealer is right for once?

Thanks as always for any help.

Did you have your jealous GF reaching on the dash for a ring ding right before the wiper problems??

:lol:

I also had this problem once. The wipers came on by themselves on intermittent, (switch was in off), but also worked in high speed. Subsequently my headlights came on as well. Not wanting to scratch the window I pulled the wiper fuse out, and left it out for the rest of the day. The next day I had to put it back in, (as it started raining), and they started again. Then as I was driving, they shut off, and everything has been fine since. I don't know what I did, if anything, to cause/cure the problem, but that was almost a year ago, and it hasn't bothered me since. (Hope I haven't jynxed myself). I don't have any help to offer, but, hey, at least you know you're not alone....maybe all marauders are possesed, (which would be great, because who needs a alarm system when you have a self-repairing, jealous car that takes it upon itself to kill your enemies :D). BTW, I did not have an aftermarket alarm, so that couldn't have been the problem.

Was going to open a new thread, but it makes sense just to update this one.

Took my car in this morning for multiple issues.

Air bag light blinks 1-9 then stays on: dealer says it's a "clock spring" and is ordering a new one.

Wipers: only work on highest speed, and the push-washer doesn't work either. They don't come on by themselves as some of you have reported, they just don't work except on high and don't retract: Dealer says it needs a new multi-function switch and is ordering one.

On my way home, and halfway down the block, and notice the dash lights are now on, and it's bright sunlight. The headlights are on now, in ALL positions, and can't be shut off at all if the motor is running. The sensor that detects light/dark isn't working I guess.

Took it right back. Dealer says it needs a new lamp control module. Says it's just a coincidence that it failed in the 90 minutes they had the car, and is totally unrelated to the wiper "multi-function switch" problem: Says he will order a new lamp control module.

I have read a bunch of threads here from you guys and think the two (wipers/lights) are related. (?)

Thanks for any feedback.

The wire going from the wiper motor to the light control module is a 'park' sensor. That means it is meant to inform the light control module when the wipers are parked.

You mentioned your wipers don't park... that might be fooling the light control module into thinking your wipers are always on. Maybe there is a revised LCM that does away with this 'feature' or maybe the dealer is misdiagnosing.

They're right. Your LCM has taken a dump. Same thing happened to me, and it was fixed by replacing the LCM.

OK, thanks Donny! Driving in heavy rain this morning and the wipers now started to work perfectly. So the multi-function switch scenario now sounds like BS.

Is the LCM the same as the one that controls the wipers?

I just _know_ I will sit in there another few hours and now have him tell me that it wasn't the wiper switch at all, but the wiper module.

Someone please let me know if these are different modules so I can call him in advance and have the extra module ready.

Thanks!

Sorry to bump an old thread but I wanted to share my story.

I searched around on the forums here to see if anyone else had this problem, and it seems like you do.

I switched my wipers on intermittently, but nothing happened. Only the high-speed position worked and when i turned my wipers off the wipers stayed in position on the windshield.

Driving to work today I was making a lane change, and I usually drive with one hand, so my hand slipped down to turn the turn signal on and I might've slipped and turned the windhsield wipers on but AS I WAS SWITCHING THE TURN SIGNAL ON my wipers started working again!

Long story short, my wipers didn't work intermittently and now they do. I don't know exactly what happened. I'm thinking it might've been crossed wires, the turn signal and wiper wires maybe? I'm not sure...

I don't have enough time right now to browse through and see what solutions are out there, but I just wanted to share my story real quick.

FWIW, several members had a problem with a pinched wiring harness that runs over top of the fire wall behind the engine.

Hope this helps.

Getting wipers stuck in the up position is a common problem with all Crown Vics, etc... Speaking to a taxi-cab shop manager yesterday he said after it rains drivers start coming in with their wipers pointed up. The motors are fine but something along the lines of the track or whatnot needs to be realigned.

I just had my MM in the shop on Monday for the same thing. Wiper motor was replaced under TSB 05-04-09 for "Uncommanded Wiper Operation". I also when through the high speed wiper only problem. The tech/service manager noted that they also drilled a small hole in a cup-like area that would catch water and possibly short out the wiper motor. So far ... so good !!! :D

Yeah it's funny, one of the first things I thought of was a possible short due to all the torrential rain we've been having the past couple days. But if that was the case then why would my high-speed setting still work?

hehe, the joys of tinkering with vehicles.

I have just recently experienced wiper problems on my 03 300a.I've read some other posts on this subject,wipers coming on and lights flashing on and off.I pulled the harness for the wiper motor and found rust and water inside the connector.I replaced the harness and motor and it has been working fine.Be sure to use plenty of dielectric grease.I hope this helps.

If your lights are on auto they will come on any time the wipers are on.
