I have a 01 Town & Country that the A/c clutch won't engage, I can get it to work by removing the relay and jumping the terminals, blows great cold air, normally I would look to the low pressure switch but I can't seem to locate it. It has enough freon cause I just charged it. It has the auto climate control, just wondering if that could be the problem...any suggestions? Thanks!

 

There is no low pressure switch in the system. There is a high pressure transducer that reads system pressure and the evaporator temp probe that is used for clutch cycling. Both are sensors and cannot be jumped and would require a scan tool to read them.

 

Thanks Tizzy1 for the info, I have the relay toggled to run the air right now and it works good, I'm going to try and find a used control module. I think that's the problem
