This vehicle has dual zone temp control, and blows only cold air on driver's side, but the passenger side works as normal. Were able to pull codes off the BCM: 46, 50, 52, 54, and 56. Have read online about a "common blend door/actuator problem" what tests can I do to verify this problem? Thanks guys!
