OK....not the ignition switch and I giggled the wires going to the compressor to see if the connection was bad. Compressor still didn't kick in. I thought I would next try to jump the connecting wires to the low-pressure switch for a half-second to see if it will turn on....but that seems unnecessary because I already know that the compressor kicks in sporadically. If the system was low on Freon, the compressors would NEVER come on instead of hit and miss...correct?
Thanks
