Question type: Maintenance & Repair

I have a 2004 Lincoln Town Car and the A/C is not working the compressor will work
cycle) if the relay is jumped however with the car running and the A/C on full blast it
not come on. Checked all fuses trying to figure out what it is.I replaced the relay and
still does not work. I am thinking it might be a faulty switch (the cut off switch or the hi
lo switch) or Lo Freon  any help??

Hello, In order: If freon is low, switch on accumulator (thingy that gets cold at firewall right rear) won't connect. Jump with wire momentarily to see if clutch engages-Keyon/Engine running. Make sure wires are connected at rear of compressor for High Side cut out. With a scanner, you can tell when you activate the Auto Climate control if the signal is being sent to the compressor through the above switches. If not, its the ATC control panel...quite common. Aftermarkets readily available, and very reasonable. Hope this Helps, AskTrannyMan
