I am trying to fix the ac on my dad's 93. It had blown out the condenser, so it lost all of it's r12. We decided to replace itwith r134. I replaced the condenser, drier, orifice tube, and flushed out all the rest of the system. I went to recharge it, and got a can into it. the compressor started cycling, but only 3 or 4 times before it shut off and has not come back on. it does have the automatic temperature control system. We tested the high and low pressure switches, and determined we had a bad high pressure switch. (It has code 66 stored in he computer. We replaced the switch, but it stillhascode66stored. IfWeeraseit, itimmediately comes back on. The compressor comes on if We jump power to it. Any ideas? I'm completelylost this time! Thanks!!
