Power windows and motors..>

My passanger window goes down well, but today, after about 3 months of deterioration, the window did not come back up. Am I correct in assuming each window has a seperate motor?

Yes, and they are prone to failure. I had my right rear passenger motor literally 'explode' in the door a month ago. Quick warranty fix - 3-400 otherwise (or do it yourself!)

Good luck!

What are the signs of imminent failure? Just slower to raise/lower?

There were no signs of imminent failure with my bimmer, one time they worked and the next time they did not. I've only lost one in 166,000 miles, my rear passenger regulator failed. Happy Motoring... [driving2]

My X5 driver regulator failed and while they were at it I had them replace the pasenger one too because it was showing the same signs that the driver did before it failed. It made clicking and snapping noises before it actually broke and the passengers was doing the same. The motors were fine and were reused. Note: the motor and regulator are two different parts and can fail separately.

I am assuming our 3-series are built roughly the same way?

My passenger window is also having problems -- making scraping
sounds when raising and lowering, and it sounds like it's going to
shatter when the door closes harder than normal...

What is the window regulator??? I am trying to replace the cables on the passanger door and don't know how to do it???

The window regulator is a cheap piece of plastic that raises and loweres your windows, over time they get weather beaten and crack.

I've always been disappointed in how the doors close -- sounds awful,
like a $10,000 crap car.

Compare against a Lexus, which makes a nice solid sound.

I think the poor way the doors close is what beats the crap out of the
window components, causing problems.

This is for a coupe, which has windows which automatically lower 1/2 inch
and then go all the way up as the door is fully closed. A 4-door may have
better door closing behavior.

I've had to have two regulators replaced (driver's and passenger's) over the 175,600 miles of my car. The regulators are a common item to wear out...but the motors shouldn't go out very easily.

95% of the time, it's the regulators. That's the metal piece with the slide, cable, pulleys, etc. that actually raises and lowers the glass. very prone to failure on these cars. usually starts making clicking, popping noises.

how would a person know if the window regulator is out? like my rear right passenger window does go down but there is no way it can go up so i have to pull it up...
does that mean i have to replace the motor or regulator?
also my passenger side window went down regular speed and came up very slow what would i have to replace?

i have a 01 325i... and where can i buy these parts cheap?

 

[White94RX]

usually when they get slow, it's the regulator. if you've got one that goes down, but not up, it still sounds like the regulator, but could still be the motor. does it make noise when it goes down or tries to come back up?
