Air Conditioning problem
1999 Chevy Cheyenne V8 Two Wheel Drive Automatic

The air conditioner seems to be only blowing through the defroster vents and the compressor is not kicking on. I don't know if it's the controls or something else.

First thing I would do,move the comtrols and listern for a hiss from the vacuum lines,if no hiss is heard,check the line on the vacuum tank under the hood,its probably broken.The A/C is a different problem altogether,you'll have to take it to a shop and have that checked.
