Hi...the mirror is easy enough to take off. If you open the door, there is a small triangular piece of plastic or wood depending on the trim that you have that comes off. Be careful when taking this off because the brackets seem to break pretty easy...(both of mine are broken), and they put some dark take to hold it in place. It isnt that noticeable, but I eventually will try to find a better fix. Once you get this plate off, there are three screws that hold the mirror in place. When you take these off(Be careful not to let them fall in the door well), you can unplug the complete mirror from the car. I didnt break mine all the way down because I spotted my problem at this point, but I know that the casing comes off and you should be able to see what is wrong at this point...you might even have a loose or dirty plug...I would check the connections before I took it apart any further.

Good luck.
