AC Compressor not engaging

You should still have a thermistor, the newer trucks are easier to get to. They plug into a air box without disassembly, behind the glove box. IDK if it will fix your problem, but it does control the compressor.

I jumped power to compressor from the battery and charged with 134a.
Today I took it to local shop and he discovered a ground short, so far. He had to push my truck to the side and he agreed to trace the short later. I believe nhe will find tipm is the source of short.

Just to finish
the high pressure ground was not properly working. A in depth check revealed the tipm was the problem with the ground. Instead of replacing tipm I connected a additional ground to the ground wire coming from the high pressure switch. Also a 3 amp fuse was placed inline. The clutch engages and cold air at last
first thank you for replying. Now I must apologize for asking this question on 3rd gen truck forum. My truck is 2011 2500 Cummins. Are you familiar with 4th gen? Is ac the same design?
