02 Deville upper/lower air vent actuator
My 02 Deville upper/lower vent actuator chatters for a couple minutes whenever starting vehicle, then settles on lower position . Changeing to upper or bi-level makes no difference. Where is this actuator and how do I access it? Getting error codes BO249 and BO429

B0249 - Heater/Defrost/AC Door Range Error
This is the code that is causing your problem. Sounds like the actuator is bad. I'd suggest you get a FSM by Helm Inc. before going after it (NOT Chiltons or Haynes). Ebay is your friend.
The other one is for the rear seat temp control actuator.
