I have a 2004 envoy gmc...When I went to close the driver side door the whole panel came off...how do I put it back on
there should be some plastic push pin keepers that go into holes in the metal. if you pull them out, sometimes they cant be re used. you can buy them at the auto parts store and replace them. line them up with the holes and push in. you can try the old ones, they might push in and hold.
