What is your car model / year ? Are you sure it's not just a low charge problem or is it really a low quantity of air that comes out ?
With that being said, does any one have a DIY or FAQ on this? I havent had the chance or money to pick up a service manuel yet.chronoti said:yes that does make sense i'm no sure on the 93 but there either a cable where when you turn it it moves that cable to move the vent postion or that a switch that tells a servo or little motor where to move the vents and either the cable for that is loose the motor is burnt out or the switch is bad
