Hello , Here to answer automotive questions and make you feel comfortable and become familiar with your product so there is no power to the compressor, did you check the fuses? if they are good you must check the connections are not corroded or un conected. You may need a wire diagram to see where power and ground come from. I believe that power should always be available and when the relay closes it supplies ground from the ECM. if you find the entire circuit works to manufacturers specs the fault must then lie in the ECM.Roman41087.0853267014
