Car presented with Incorrect air flow out the heat/ac vents. Upon inspection we discovered that a previous servicing facility had worked on the vehicle and left the ACC system in total disarray. Vacuum lines were disconnected, flaps were wire tied closed, actuators were disabled, vacuum manifolds were plugged, in short, the ACC air direction system was non-functional. This required removal of the dash pad and center console to fully inspect and access what was needed to make the system operational once again. Subsequently upon removal we found broken flaps, damaged cable actuators and stripped gears. This is a major undertaking, and it all has to be right before the dash is reinstalled back into the car.
