BMW Repair: BMW Window button, window button, problem thanks

Question
My cars driver side window button seems to be malfunctioning. The window works fine, but button doesn't always work to bring the window up. It works fine to bring the window down, but I often have to try multiple times to get the window to go up. I was wondering if you can tell me how to change that single button. I really cant afford to take it to the dealer for this problem. Thanks for you help.

Answer
You don't say what model of BMW this is, but for most, the switch comes out of the panel, and is easy to replace.

I recommend going to this site for finding the replacement part to your specific BMW.
