I recently tried to follow the instructions at Diesel Giant to remove the drivers side door panel, to replace the vaccum valve in there, but he must've been using another model as and example. When I got everything apart, and was ready to remove the panel something was holding it and I couldn't bring myself to pry any harder 'cause I didn't want to be picking pieces of it up off the garage floor. Felt like what ever clip or pin was holding it, it felt like it was toward the center of the panel..... any ideas?
