Part in the blower box that has the wire coils on it?

Thank you Mr. *******.

Let me stretch this a little further. I had asked some of these questions a couple of months ago, but maybe I never worded them clearly. I changed a bunch of AC parts including the accumulator, which has the new cycling switch. during this time I unfortunately did not tie off the pigtail that plugged into it. The pigtail fell down onto the exhaust manifold, and needless to say it was toast. I got a new pigtail, and wired it in as best as I could. There were two wires into the pigtail; an orange and a green, and there are two white wires that go to the nether regions of the wiring harness. No matter which way combination of wiring I do, the compressor will not kick on. It will not kick on with the two white wires together either. I have to jumper all four wires together to get the compressor to come on. Needless to say, the compressor stays on all the time and I have to manually cycle it sometimes to let the evaporator core thaw out. Not a good situation.

The AC cools just fine; therefore I do not believe it is any kind of pressure problem. For giggles I tried adding more freon to see if the compressor would kick on while I was adding, but no luck. Any ideas? Lets say I change the cycling switch and no change. What do I check next?

Thanks,

The low pressure switch on the accumulator is also called the cycling switch. Yes, it can be replaced without drawing down the system because there is a schrader valve in the fitting on the accumulator. Try to change it quickly, because sometimes the schrader valve will leak when you remove the switch. Easy replacement.
Good Luck and God Bless
