I just bought my Heaven on Wheels (04 black 1 owner LT with quads, dvd, 73k) a month ago, and now the rear doors won't unlock with the fob or switch, but the tailgate does. They lock with either (fob or switch), but never unlock? My other question is regarding my third row seat-I can't get the #1 release to release. When I pull up, the seatback moves a little, but not very much, and you Suburban owners know that you can't take the seat out unless you can get that seatback folded over. Any help from you wily vets would be much appreciated.
