It sounds like the regulator and lift assembly has broken. The door windows have a gear-drive motor inside which spins to drive the window up and down. If the gear teeth have broken or been stripped, or the corresponding teeth on the window have stripped, it'll make that noise.

What you'll need to do, assuming you're going to fix it yourself, is to remove the rear door panel. Most cars have a screw behind the door handle (pull on it as if you are going to open the door, and see if there's a screw there). You'll probably have one or more screws on the side edges of the door panel too. On my Audi, I have to pull off the plastic inner cover of the door pull (where you pull the door closed) to expose another mounting screw. Since your BMW is a similar type of luxury car, yours is likely similar. Once the screws are out, try lifting up on the door panel from the bottom. If it doesn't move, pull it straight off the door. Some cars use guide hangers that just slot into the door frame, while others have snap clips that require the panel to be popped off. Once it's free, don't move it too far until you disconnect the door latch rod and the electrical connectors.

Now you should see a drive motor with a wire connector going into it. There are likely to be three or four bolts that hold it, and once they're out, the motor will pop off. What you can do is pop it off, and take off the one on the other door as well, and swap them. Try each window. If the failing door now works with the other motor, and the working door does not, then that's your problem. Order another one (see below for a great source) and install it, put the door panel back together, and you're on your way.

Now, if the drive motor wasn't the problem, you're going to have some gymnastics to do. I take it that the window is stuck down. You're going to see that the door framework itself has some holes in it. There are also some bolt heads that you'll see. Those bolts hold the lift mechanism in place. The cutouts are placed strategically but not all that conveniently, and you'll have to do some contortions to get everything undone. All the cars I've worked on require you to position the window at one height to get some bolts out, and then move the window up or down to get others out. With the window stuck, you'll have to take out the bolts that mount the whole mechanism to the door, so you can lift and lower everything manually into the right positions to get at the bolts that hold the window glass to the regulator, and possibly some various parts of the mechanism itself. There's really no cut and dried way to describe it, since all windows are different, but the bolts that attach the glass to the lift are at the bottom edge of the glass, and there should be two of them. Have a second person handy, so they can hold the glass from both sides while you take the bolts out. Then lift the glass up and out and set it aside where it'll be safe. From there, it's a matter of removing all the bolts that hold the mechanism, and pulling it out of one of the cutouts in the door frame. Installation of a replacement is the same in reverse order. If you need to source one, I'd recommend www.shokan.com in upstate NY - they're a salvage yard for BMW, Audi, Mercedes, and VW, and they guarantee their parts (they're a forum sponsor for one of the online enthusiast forums that I moderate, and are highly regarded).

Let me know if you have further questions on this (post them as a follow-up comment here) and I'll address them:)

What would cause my Aztek to make loud grinding, groaning and now sounds like something is broken in the rear while driving?


My hunch would be rear wheel bearings. Lift and spin each wheel listening for noise is all I can suggest at this point.

Passenger window does not go up or down . window fell in side of door and will not go up . when you push button there is grinding noise inside of door and window does not go up.


sounds like the hardware that holds the window to the bars which raise and lower the window has come undone (a bolt has came off) and the window is no longer attached to the lifting assembly.

while not terribly complicated, this is not a job for one with no knowledge of the mechanics of power windows... but even a stero installer should have the skill to fix this easily and cheaper than a dealer

Passenger power window on my 1998 vw beetle is making a grinding noise


It sounds like something is catching as the window moves. Could be the cables (if it has them), guide rails, etc.
You'll need to remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. You'll need to lift the door panel upwards in order to get it off the window ledge. Then pull back the weather seal and work the window up and down and hopefully you'll be able to see the cause

The power window on the passenger side went down, with a lot of noise. But now it won't go back up. I hear the motor making all kinds of slipping and grinding like sounds.


The wiz is abslutely correct. When you have it repaired just make sure that the mechanic who works on it verifies that the window is still firmly secured in the rail.
