I have a 2006 dodge truck 3500 ram, turbo diesel. Have a code p1275, and an intermitant ac clutch operation. If I jump voltage to the compressor it will come on, after a few minutes I can disconnect the jumper and turn off switch inside - then on and it will come on and stay. If I let the truck sit and cool it will not come on. Can you help, Steve G.

 

sounds like you have a low system charge, need to check the pressures
