So we have an 01 Aurora and the A/C does not blow cold. Have checked the a/c clu fuse and relay. Both are good. Compressor seems to not engage (can't hear it come on when turning a/c on). I had heard that the temp sensor may dislodge, leaking coolant. Where would this be and how do I know for sure whether the compressor is bad or not?

thanks,
Derrick

 

Do you have gauges?

i'll check into getting a hold of some
