did you get your ac running
When the A/C stops working, check the power supply to the A/C Compressor, this will give you a good idea as what to do. If it has power and the compressor is not working, it probably needs a new a/c compressor clutch. If there is no power, you will need to diagnose the control side of the circuit. This will require a wiring diagram and some electrical diagnostic experience.
my 2001 ram 1500 does the same thing. still trying to figure it out. i am about to try a new compressor out of sesperation. 3 weeks of 100+ out side
