How do you replace the drivers side mirror on a 1999 Suburban?

If your door is the same as my 1995 Silverado, at the top of the door panel inside, opposite of the mirror assy. is a triangular piece of plastic. push this piece upward, it will come off exposing the mounting screws for the mirror and the wiring harness and the connector. Been there, done that.

Ed in Lanesboro, ma. Let me know how you made out.
