Replaced them and still the same problem. That leads me to believe that my problem is with the sensor that is in the tube that comes from the condenser (High pressure switch?) It seems that the only way to get this sensor is to buy part#73431(I).which is (Pipe-Condenser-Liquid Tank). Anyone have this problem before? |
That sound like the high pressure switch. My dealer looked it up and it only comes with the high pressure pipe/hose. It's around $100. I haven't switched over to 134 yet and am holding off until the AC starts acting up again. At that time, I'll replace that line/switch combo and do the conversion.
When I described the way our AC's are behaving, a couple of automotive HVAC guys I know both said it sounded like the high pres switch, so this sounds promising.
