AC Output OK on Defroster and Feet, but Not Front Vents Note: On the dial, front vents (the ones not putting out air) is to the left, feet in the top middle, and defroster to the right). AC AIR CONDITIONING PLEXIGLASS TUBES VENTS Maybe GM 1954-1955 Buick/Cadillac?, VINTAGE CAR & TRUCK UNDER DASH HEATER BOX UNIVERSAL PACKARD FORD CHEVY BUICK, HVAC Case Seal 1970-1972 Buick Skylark 4032-379-681S, A/C Defrost Heat 2. I have a 2001 S10 Pickup Zr2. Features choice of integrated control package or Electronic slide control that fits into the original dash opening. What is the problem and how can I fix this? AC won't switch from defrost to any other setting. AC stuck blowing only out Defrost Vent I have a 2005 Magnum and just last week, I set the ac to flow out the Defogger to clear up some fog on the windshield, and now. The air conditioner blend door is controlled by an electronic actuator and if the door is not in set position then you may have a defective actuator and need to replace it. Defrost without A/C mod. 1999-00 Chevy C2500 Truck with Rear Defrost. I tried changing it form auto to all other settings, and it's been through a few restarts since. The primary reason you are hard pressed to order a GM vehicle without AC anymore). AC stuck on defrost??? Asked by zach1990.
