The door comes apart easily... you need a small torx driver and a crosshead screwdriver. Pop the little cougar cap off the inside of the door and the plug lower down and undo the cross head screws underneath, then undo the small torx screw at the top inner edge (hinge side) of the door edge and the two screws on the outer edge. There is one more long torx screw on the inside of the door liner at the inner bottom through a little hole in the fluffy felt to remove, then just pull the door liner sharply at the bottom both sides till it pops free, then lift the door liner off the door and unhook it. The wires and door lock cable stop it going far but you can get to the relay or the speaker.
