how to replace the power window switch on 2005 BMW 325i?



Use a screw driver to gently pry away the wood trim. Put the trim in a safe spot:

On the armrest you will either have a window control, a side mirror control, or a blank plug. (On my passenger side I have a blank plug). This will need to be removed. On the driver's side I was able to use a screwdriver with a very thin tip to remove it without any problems. On the passenger side, this blank plug was very deep in the hole and the screwdriver was not working. I could see that if I really forced the screwdriver in there it would have damaged the leather. Not really knowing what to do, I started looking around the house for something I could use to get this plug out. I tried this Wustoff carrot peeler and it worked great! No damage to the leather. I think any peeler in this basic shape should do the trick. You might also want to try removing the plug at the other end if you are having trouble. Sometimes removing the plug on the side that is higher up the arm is a little easier. If you have a window control or a mirror control in this spot, once you get it out disconnect the wires that are attached to it. Put the control in a safe spot:
