How to repair back door on 1997 chevy suburban?
There is a handle in the door jamb of the left hand door, viewable when you open the right hand door, if that handle doesn’t work the rod or rods may have come off the handle. you will need to remove the panel on the inside of the door (some models are screwed on and others have clips and should just pry off) then look to the left if the rods popped off you could try to reattach them and open the door. The rods are held in place by little clips that will probably be found inside the door, if not stop by a dealership or body shop and get new ones then put the panel back and you should be good to go.
