I had the exact same issue on a 2007 suburban. No power to Passenger side door, no window, no remote lock and mirror on passenger side door. Also had no control to that side with the driver side controls.
Took me 15 minutes to repair. popped the driver side electrical button panel on the driver side door. Reseated all control connectors, on mine was three. Sprayed WD-40 on them before I put them all back. Popped the panel back in! And all worked once again.
