Power Window not working

Hey guys

New here, recently bought a 2000 model 323i and the rear passenger power window doesn't work. I am pretty sure it was working when I first viewed the car. What are some basic things I could do to try and fix it without replacing parts or opening panels? Also might be worth noting that when either front or back buttons are pushed, there isn't a noise from the motor.

Thanks

If all window regulator aren't working look for a busted fuse and replace. That doesn't mean its over though. Fuses blow when they draw too much current so you may still need to track down the regulator that is causing the fuse to blow.

I will put my bet on it being a window regulator. After you check the fuse--that is the place be be thinking. In the 7 times I have changed window regulators, never had to replace a motor, so my guess is that the motor is okay. But when you open it up, deal with it then.

The regulators go out on these cars often, search around and you'll find some insight. Depending on the issue, you may be able to fix it with zip ties if I recall correctly...Haven't had to deal with this issues on my own yet.

Although I have read that some people have used (tried to use) zip ties--my experience has always been that zip ties will not work. Every case where I opened up the door, the cable and plastic pulleys are so far gone that the zip tie answer would not work. AND, I would not want to invest the time in opening the door and not putting in a new regulator after doing all the work.

Thanks for the reply, would you think it would still be the regulator if the window doesn't move at all and the motor doesnt make any noise?

Yes. As I have said, I have changed regulators 7 times and every time had exactly the same thing when I removed the door panel. Always found that the cable snapped loose and was wrapped around part of the regulator making the regulator and cable beyond repair. Normally the plastic anchor that holds the cable in place is broken--but the damage to the cable and perhaps a pulley is beyond repair. And yes, the window may not move manually because the cable is so tangled into the regular that it locks the window in place. But sometimes you can manually move the window closed and tape it into position until the new regulator is installed. Not sure if this is the case with other people--but that has been my experience. The motor was never broken in all my situations, and all seven times used the original motor. I do not think you will hear the motor unless the panel is remove--too quiet. But I would NOT work the window switch because if the motor is trying to pull the window open (or closed) and if is locked in place due to the tangled cable--you may strip the gears in the motor and will need a new motor. Here is what I would do if I was you. Remove the door panel. Carefully remove the rain guard so that it can be reused (or buy a new one if you are careless). Look carefully at the regulator. You will spot immediately if the cable is loose and tangled. At that point get a new regulator if it is that. Also check to see if the motor is working, and if not--order the regulator with the motor. The last three I purchased were After-Market and cost about US$70. Been in service for close to 2 years. All other regulators were BMW--but needed twice to replace the replacement regulator--clearly these regulators are under-engineered so I am not so keen on BMW regulators which cost about $120 (US).
Good luck and let us know how you did. One last point--that is critical--MUST reapply the rain guard plastic perfectly sealed or you will get a flood of water into the carpet of your car. Read up on this.
Also the price the dealer charges in the US to do this work is anywhere from US$ 400 to $700.

The cable tire does work if the damage is minor. My windows still works but I can here clicking sound. I found the plastic clip holder has a crack, so I super glued it, then applied cable tire. Now the clicking is gone. Don't know how long it will last though, but the cable tire will reduce the stress on the plastic holder.
