no I didn't, I would like to. Is opening the door panel a big job? I'm always afraid that I won't be able to put it back together again afterwards...
Where can I get good instructions ?
It's just a few clips. Taking a knife (not a sharp one, just flat) and wedging it between the door and the plastics with a gentle pry it should come off. Chances are you'll snap a couple of clips, You can get new clips in an auto supply store if you need them or from amazon/eBay for cheaper. You'll need to just do a drop of research to determine which clips are for your vehicle.
When pulling the plastic off the door you should pull next to the clips to avoid cracking the actual door plastic.
