before we got the truck back, the previous driver did something to the AC system that only allows it to blow through the defrost vents. ive taken apart the dash to replace the stereo with a factory unit i got from my friends 05 lariat and didnt notice anything wrong with the ducting in that immediate area. the AC is cold and the compressor doesnt cycle like crazy.
any advice you folks can give me to get the AC working back properly to where the selector can actually select where to blow the air? haha. i know its gotta be something simple. i just need to get the truck back to proper functioning form to get it in to the dealer.
any and all advice is appreciated.
