So question, when the door is locked and you pull from the interior it first pops up the little knob indicating the door is unlocked, then you can open the door. The "broken" passenger door still can push the little knob up, if the cable was broken would that link also break? If it's still connected, would this then mean the door is still locked and a GM5 issue?
From the outside it feels exactly the same as the drivers side door (which works) and from the inside it feels the same as well, it just seems locked.
Anyone know how much it would cost to diagnose at a dealer? I would rather not buy a new GM5 if it wasn't the culprit
