ac not working

Hello, If jumping the relay works, but powering the relay from inside the vehicle does not, there is an issue in the electrical circuit between the A/C on button and the relay, or between the relay and ground/power (depending on the polarity of the circuit), or the A/C may be disabled due to high or low pressure, incorrect refrigerant temperature, or a number of other faults that the control module will notice. It may be best to scan this vehicle for codes and A/C operation before continuing to run the compressor.
