H2Much, Just about everything is gone as seen in the one picture in the above link I referenced, sensors, electrical, mechanical, compressor module, compressor itself, all went bye bye
Might be a couple wires left under the dash and hood that were a pain to get at but when I was done removing everything that I could get out of the truck I disconnected the negative battery cable for a bit to reset the "computer" and the light on the dash has never came back on.
If you still have sensors and the compressor module and the like in the truck the computer is looking at them as not working and then throwing the code is all I can think of
HUMTECH might have the correct part or parts that need to be removed but I think with me using the grenade approach I hit upon the right part by chance.
