Sounds like either you door switch or your interior light switch possibly bad. These are smart switches and carry a resistance value that the Switch Hub Module recognize. Does the interior ligh switch open the door? Do you have access to service link?
Most likely the door switch or the micro switch,s metal contact arm on the backside of the door rods on top of the rearward door leaf. the switch sometimes comes loose and the bracket as well. we have moved the switch to the backside of the bracket but in order to tighten the screws you have to skew the back half of the switch retainer at an angle to get the tabs in the bracket holes and readjust the closed door position. TBB104539 is the door switch number.
