2nd Gen Non-Engine/Transmission air conditioning help

[cluckmaster]

My air conditioning compressor is not spinning. Fuses and relay are good. Jumped the pressure sensor on the line back to itself and still didn't spin. I don't thin the compressor is bad because I had cold air when my truck went down a month ago, and I had the head off, timing cover off, etc. Now it's back together and this problem popped up. Any ideas?

Compressor clutch? Low pressure cycling clutch switch? Compressor clutch relay?

High pressure cut-off switch, I believe this is the one you jumped.

As MM says, try bypassing the low side switch, it is in the receiver dryer or suction line to the compressor. You probably lost the refrigerant while the truck was down, broke a line or punched a hole in the condenser. Hope not. bg
