Seems like the compressor is not getting power?? But there is power @ the relay...Relay is not bad cause i swapped them with the other ones and it works fine...ANY IDEAS ON WHAT WRONG??? HELP!! don't know what next to do....
Check the relays coil side voltage across the coil with a voltmeter with the A/C button turned on, if there is no voltage than it's an issue with the wiring maybe a short or a issues with the A/C control in the dash. It is possible also but doubt it that the low side or high side pressure sensor is dead.
