Hey... I am new and hunt's friend with the Tahoe. I am baffled... All at one time the remotes quit responding and the passenger door lock button quit working along with the power window on the passenger side door. I can unlock the door with the key but that is it. Also when I use the lock button on the driver's side it unlocks the drivers door, the back two doors and the rear gate but not the passenger door. Looking at the fuse block diagram in the manual it mentions door lock relay's and also mentions something about a right door control module (RDCM)and a left door control module (LDCM). Do any of you guys now anything about those? Any help is appreciated. Thanks.
