A/C problem

[R/C flyer]

i have a 97 f250 heavyduty 7.3l the air work good when the truck is moving but when you stop at a light it will start blowing warm air then start moving it gets cold again. i was wondering if it was a low charge, bad compresser, bad clutch on the compressor, or possibly the fan fluid clutch bad not moving enough air. any input would be a great help dont have a bunch of money to throw at it. the air also worked great last year.

Try a recharge and cleaning off the condensor, I did mine kause air was kinda Kool at idle now blows nice and cold again. Blows colder the more air you move across it.
