I would look at the air blend doors first, it sound like they are not working or your control in the dash is not working send a signal to them. they work by changing the air from hot to cold or in between.

common problem, check under dash by the gas pedal if control arms are muving went selecting from ac to heat cuz this it is the control for the vents to go from ac to heat and to defrost.

Ok, here is the scoop on this. if you sit in the passenger seat and reach under the dash in the center of the vehicle. So your laying in the passenger side of the vehicle and placing your right hand on the floor board were passengers feet would go, slightly to the left of there is where the carpet raises up to the center hump behind the button for emergency flashers. Ok there you will see or feel a plastic small arm attached to a wire rod. this plastic arm is most likely broke or like mine the its worn, so push it back inside the small hole, while turning the heat switch from cold to hot. All this little arm does is open and close the heat vent, but also allows the air conditioner to fully turn on. As you turn the heat switch you will see, or notice it catches the mechanism and the heat will switch on or the air will come on as you turn the switch. I had only a few minutes left to short fix this so I opted to glue the darn thing in place, yes a quick fix but its working and after only looking and poking around I now know what this is so when I have time i can fix it. My own mechanic whom I trusted for years said look its the heater box major repair. I know he doesn't care to work on Vw's its all good but it cost almost nothing to repair this badly designed item. I was ready to sell as is and take the hit but waited one more day when I could find my good flashlight and just refused to believe I had to take off the dash. So dont go to dealer unless you have the time and you point out whats wrong, they also said it was both the air compressor and a cracked heat box? find and locate it yourself I don't have a warranty on this 2002 1602,000 mile car, but I keep it running with good maintenance and all you who are kind enough to keep us all updated on your finds.
