Hello, My name is Jack and I have a problem with my 1991 Town car, and I don't think that you will be able to find out the problem. This will take some time to explain this, so here goes. Seven years ago I had the air changed over to R134 and since then have had nothing but head aches. First it would freeze up the evaporator and would loose air flow. The compressor did not cycle and the dealer told me it was not supposed to. I have had several people tell me it has to cycle, and some tell me it does not. To make a long story short I will fast forward to the present. I have gone through 4 compressors and have changed everything [ cycle switch, orifice tube, dryer, new hoses, muffler ]. The only two things I have not changed is the evaporator, and the condenser. We cannot get the compressor to cycle if it is supposed to. We put the gauges on and all the numbers are fine. We are at a loss, and are pulling our hair out. I have changed the fan clutch thinking this would solve it, but no it did not. I have had it at Lincoln and THEY could not find the answer. We just do not know what to try next. It will be something stupid. I will appreciate any tips you could give me to check on, all though from what we have already done I don't think even you might not be able to help. Thank You in advance for your help. Jack, I told you this would be a hard one for you. We just can't get the compressor to cycle and if you can find an answer I would gladly donate to you. Thanks Jack
