Default AC Compressor Won’t Kick on

75 with factory air using 134a. AC has been working fine until the other day. Ran power to the compressor and clutch engages. No voltage to the TAN wire at the low pressure limit switch. 30 Amp in line fuse is good at resistor. When the head shell is rolled from off to AC Max no clicking at the compressor clutch but fan spreads work in all positions.
Thinking a bad AC switch in head control or could it be the AC resistor in the engine compartment? How would I determine if it’s these items or should I look some where else for the problem?
Any help would be appreciated because it is finally getting worm in Michigan!

Most likely you’re low on Freon. It’s a safety feature for the compressor to not run if it’s low.

Don’t think that’s the problem because their is no power to the low pressure switch.
