By passed low pressure switch to engage clutch, tried to charge thru ac gauges low side. Compressor not sucking in freon,tried one of those quickie dispensers just in case there was a problem with cheap HF gauges. It still wouldn't take gas. I suspect a problem within the compressor. I've had a course in ac but no expert by any means, I suspect a problem within the compressor itself. Anyone had the same problem and found a fix?
