My passenger door on my 2000 GMC Sierra won't open from the inside. The
slide lock just flops back and forth. The inside handle pulls out like it is
locked. I can open it from the outside by inserting the key and holding it
in the unlock position and then pulling on the outside handle. When I close
it again, it is locked again. The door panel on the inside looks like it has
been pulled away some. It seems like the top clip that holds the panel to
the metal door broke off (it's a plastic clip). I don't know how that
happened. I have googled for gmc door locks, and 2000 gmc sierra door, etc.,
but I have not found anything helpful.
I do not have power windows, or anything fancy, just the basic manual door
locks, and manual crank windows. The truck has just the 2 doors. I was
thinking of taking the door panel off to see what is wrong, but thought I
would ask if anyone here has had this problem, or if there is a web site out
there that may have a diagram of what's inside the door ( e.g. linkage and
clips) ? Any help is appreciated.
