Cadillac Seville Improper HVAC Temperature and/or Air Delivery Due to Failed Mode Door Actuator

(23 reports)

One or more heater & AC (HVAC) air delivery and/or temperature mode door actuator may fail. This can result in incorrect air delivery or temperature. If this occurs, fault code(s) stored in the HVAC control module should be available to assist with diagnoses.

AC blows out heater and defroster vents and NOT out the dash vents where it is supposed to come out. It's not fixed yet but it seems to be a control or lack of control problem as in actuators failing or something like that. -
Both air blending actuators (driver's side and passenger's side) are working fine. Rear mode actuator (on drivers side center console) is also working fine. These are all easy to get to. The front Mode actuator is not functioning. I want to R&R it. How can I get it out? I suspect I need to remove the Climate control / radio unit. How is this done? -
