DE | IH S2500 truck , 30 lb low side, 275 high side. Outside temp was about 80. AC output was between 55 and 60 degrees. I blew/washed out the evaporator had some chaff stuck in it. It worked great last year. Did not add any freon. Hi pressure line to compressor was hot and low pressure line was cold and a lot of condensation was dripping from evaporator, very humid today. I'm thinking the expansion valve is the problem. Condensor is clean. This is 134a. | |
