Any suggestions on exactly how to remove door panel?

First, make sure there are no screws still in the door. Sometimes they are covered with a cap that makes them not visible as screws. You can pry off the caps and then use a screwdrive to remove them. After that, I suggest that you gat a long handle flat head screw driver, put masking tape over the head (to keep it from scratching anything on your door panel) and then slide it between the door panel and the door frame. You wil need to slide it around to find the lastic clips that connect it to the door frame and then apply pressure by pulling the screw driver up against the door panel. This should release the clip...YOU MAY BREAK A FEW CLIPS, but don't worry, your local toyota dealer will sell you as many as you need, and I've noticed that even AutoZone sells them near their hardware section in the store. You will need to keep some outward pressure on the door to pry it away from the fram and that should do it... After it is all pulled away you will probably have to slide it up out of the windw track and you should be all set. Hope this helps... Good Luck!!
