Several different reasons exist for removing a door panel on a Chevy Silverado. Side window repair, speaker replacement, window control module, window motor, upgrading to a directional side-view mirror (one that displays the directional light on the mirror when you turn on the directional switch) or even replacing the door panel itself are all reasons that require removing the door panel. The procedure is not overly complicated, but there are a few precautions to take into consideration.
Open the door and power the window all the way down if possible. (If you’re replacing the window motor and the window does not work, it’s not required that you have the window down, but it gives you more room to work with without the risk of scratching the window.)
Remove the side view mirror sail located in the upper corner of the door panel. This trim piece covers the interior side of the side view mirror. Pry it off with the small, angled trim tool from the top and rear side.
