Unhappy Loss of A/C at idle with Unorthodox Pulley?

Since the weather has been getting warmer, I've started using the air conditioner, and noticed recently that when the car (1999 Outback Sport) is idling, the aircon shuts off and the fan only blows uncooled air. The cold air flow resumes once the car is moving. Is this normal? It just occurred to me that it could be the result of the A/C not getting enough juice at idle because of the pulley.

Anyone else have this problem?

I have the pulley and have not had a problem at all, yours may be a faulty AC, maybe out of gas or something...

It can't be gas if it was it would never be cold it would just blow hot air I would definitley have it checked out I wouldn't think that an underdrive pulley would cause that but you never know.

Yes its the pulley causing the A/C not to work very well. The Air conditioner compressor runs off the pulley or crank shaft. When you put the smaller diameter pulley on, you slowed down the speed of the compressor. My A/C does that too (I have the UR pulley). I wouldn't take it to the dealer unless you want to pay for them to tell you that you need to put the stock pulley on and maybe they will void you for future warranty issues because they will know you have put the pulley on.

Hmm.... I have the UR pulley on my 99 OBS too. So far no problem. It might blow less air. But it is definitely cool air. I thought the cool air is with the CFC free gas?\ instead of the a/c fan.
