So last week my driver's side window regulator went out and I swapped it out today for a new one, bolted everything back up and gave it a whirl. For some reason now, the window goes down when I hit UP and up when I hit DOWN!!!! What gives?

 

nobody has any ideas what happened?

 

sounds to me like you switched the motor wires around/ need to switch them around.

 

problem is... thats impossible. I didn't touch the wires. all i did was unplug the harness from the motor to get the regulator out of the door.

 

The harness can't be plugged reversed? If not, maybe you got a passenger-side unit rather than a driver's side.

 

no. Its definitely the correct regulator, the motor just transfers over from the old one to the new one, so nothing changed, i don't get it...

 

If everything is the same and the unit is the right one for the door and year, only one other choice - the new motor was wired wrong when it was made.

 

Like I said, it isn't a new motor. The old motors transfers over to the new regulator.

 

No motor change, no wiring change, part is correct, and reinstalled exactly like the one it replaced? Poltergeists? I'm tapping out on this one.

 

This is so weird. I had another guy call me with a similar problem, but don't think he fixed it yet either. I'd be interested in hearing what you figure out. Something simple is wrong with it.

 

I remember hearing something about holding the window switch in the full up postion for 6 seconds after it is closed if you have any problems...sometning about re-initalizing it. Might be worth a shot...free to try before you swap wires or anything.

 

I took the motor out and cleaned it in my 02 r50 reinstalled it and have the same exact problem. up is down and down is up. If someone comes up with a solution Please it would be very helpful.

 

Didn't want to start a new thread for the same problem. I just replaced my window regulator and motor today. My old motor still worked, but the new unit came as one with the motor, so I didn't bother using the old. Anyway, I followed the instructions on Pelican Parts, which were easy and pretty straight forward. Now, my up is down and my down is up. Anybody have any developments on this. It's been months since I purchase the new regulator, so I can't exactly sent it back.

 

I have recently replaced my passenger regulator & have a different, yet possibly related issue:
Mine functions like normal but sometimes, if I let it go all the way down, it refuses to come back up. When it happens, it'll begin to move but only dips - like it does when you're closing the door!
Once this happens, I have to disassemble the door, take the rear regulator section loose & pull the assembly upward, forcing cable to move. This causes things to get happy again until I let the window go all the way down again. Kooky, eh?
I have noticed that when it's completely down, it rests deeper in the door than it did with the old regulator. Related? Maybe so.
If I ever finish my maintenance laundry list, I'm going to disassemble the door again & raise the window in the cradles a bit. Maybe that will help..
And yes - I've reset the system (holding the switches up) numerous times.
Wish me luck!

 

Original poster: Ran into the identical problem today with up being down and down being up on the switch. Could not figure it out either so assumed that the manufacturer of the motor reversed the leads on the connector to the motor. I cut the leads to the plug (on the car side) and reconnected them opposite from the factory. I hated to do this but the part was mail ordered and didn't want to do without a window while I waited for a replacement new part. Motor/regulator worked perfectly after that and the "dipper" worked correctly at the top of travel as well. I was able to reach the connector without removing the regulator assembly so the fix was relatively simple as the door panel was already off. If you haven't fixed yours yet, I think this will correct your problem.

 

I think your motor may be in backwards. I had to take apart my passenger motor to clean it when it stopped working, and the guide I was following specified something along the lines of "make sure you put this back in facing the same way it came out or your power will be reversed". I don't know where the guide was to double check, but I'm pretty sure they were referencing the motor.

 

I did a little more research to dig up that guide that I used. It was on MINI 2, and I'll link to it below. It sounds like you have your motor casing on reversed 180 degrees. Maybe it has something to do with the polarity of the magnets. About 1/3 of the way down the page, he says this:

"Important note, mark which way the casing goes in, if it is out by 180 degree your motor will function the opposite way !"

reply the casing for the motor which has the magnets in it is symmetrical and can be installed 180 degrees off. This will give you reversed operation and is not uncommon for aftermarket parts company's to do this. The only variable that has changed since your window worked properly is the motor. I have experienced this from aftermarket parts and done this myself rebuilding motors.

 

I had the same "up is down" situation when I replaced my driver window motor on my 04 S and learned it is common for aftermarket motors to be assembled backwards and run backwards. It can be fixed by turning the motor case 180 degrees or by swapping the wires in the wiring harness. I made up some jumper wires for mine to reverse the wiring because I didn't want to take the assembly back out or cut the harness, but I did try the 180 on the new motor for the passenger side that I had not yet installed and it did reverse the motor's direction. I'll check the rotation of the OEM passenger motor when I change it to make sure the new one turns the same way.

 

I had the same problem with reverse operation of a new window regulator. The one I bought came with a pigtail that the instructions said I shouldn't need, but with that pigtail installed it works correctly.

 

Today I received an email with this information, but following the link I don't see the posting.

Dear philwarner,
Linux Diner has just replied to a thread you have subscribed to entitled - Reversed control on window regulator fix??? Weird. - in the Stock Problems/Issues forum of North American Motoring.

I thought it nice that this seller sent a pigtail to reverse the motor wiring "if needed"; I had to make my own. As a followup, my passenger side motor worked correctly after I turned the motor case 180 degrees before installing it. I guess you have a 5050 chance of a reversed motor when buying aftermarket and in my case both driver and passenger motors came reversed. both are still working, though, after more than a year and were a whole lot less than an OEM replacement.

 

There is a lengthy discussion of a similar issue on the Lexus forums, only the motor is in the door locks, not window regulators. But same problem: replace the unit and it works backwards. Apparently the problem can be traced to a Chinese manufacturer of the motors; lousy quality control as to the polarity.

 

If you replaced the motor, some of the aftermarket motors had the case installed incorrectly as others said. take it back out and rotate it 180. plug it in and check operation prior to reinstalling, save you many headaches.

 

I just installed my new regulator and motor assembly in my 03 R53. Passenger side. It operates backwards as all have described here. Some have mentioned fixing it by turning the motor 180 degrees. Do any of you have pictures?? I don’t see right off what you are suggesting to move to fix the polarity.

 

There are 2 screws holding motor to plastic regulator housing. Remove screws an twist motor 180 deg. The reinstall screws
