Im helping a buddy with an 06 2500 with a/c problems. His compressor will only turn on if it is jumpered to the battery. We tested the wires at the connection and there is 12volts there, but the comp won't turn on with just the connector plugged in. The pressure switch by the pass side tire is new and it is showing around 40psi on a cheapy gauge.
Could this be a TPIM issue? We're at a loss since we have 12 volts at the compressor connection.
Thanks
Ian
