How do you remove GMC truck 1990 door panel with power windows?

if it's the drivers door

the is a plastic strip about 1 inch wide and 8 inches long with 3 Phillips screws

(remove)

there are 2 screws on the door handle

(remove screws)

the panel is then only held to the door by some push in "clip" plugs

pull on the panel

start on the bottom

then the sides

then lift up

the power window switch has some extra wire so you can get the panel off

but you can't get it too far away

enough to get in and work on the door handle, lock, or window
