1998 Chevrolet Silverado, 93K, blows nothing but hot air. No funning noises from compressor, the air is just hot. Any advice before taking to repair shop appreciated. Thanks
No difference when the temp setting is changed eh?
When did the A/C stop putting out cold air?
Was it a gradual decline in performance or suddenly?
Perhaps the A/C has a leak causing a loss of refrigerant, loss of drive belt, maybe the A/c is plain tired.
Does the blend door operate properly? Is the switch/lever working?
