Clarke,

I had a brain fade yesterday when I heard you describe your loss of air flow with the AC problem. I don't think it's your fan. I think your gas level is low. The first clue is the previous post. When the pressure is low in a refrigeration system you get very low cooling temperatures. Those low temps cause the water in the air to actually freeze on the evaporator unit that the fan blows across. When enough water freezes the air stops going through. Put some gauges on the compressor and have the pressure checked. When the low side pressure gets really low, a switch will keep the compressor from coming on, but before that happens you will blow ice cold air, for a little while.

I feel like a dummy cause I had gauges and 134a in the coach with me. Doesn't really help that the answer came to me when I was almost back to Fort Worth. Sorry.
