ninety nine viggen the acc doors when trying to change to defroster vents or floor doesnt change to the direction desired what can this be? the motor itself a type of drum? what is the common problem with this?
theres a weird grease that causes the door to stick.
there were a few service bulletins and methods of placing screws in certain places to pull the outer sides of the box away from the flap giving it more freedom to move. i dont believe either of them are perfect tho, and they are quite a pain to perform.
lol welll im going to need to use the defroster and the car only blows hot air anyways...idk i am looking to buy this car and i want to have the system working....my 2000 9-3 never had the problem but i never used the acc system as i love to drive with the windows down..and only used heat in the winter.. sooo where can i find this service bulletin?
