So my ac fan 1 is not turning on when we “hot wire “ it the fan turns on then it gives us ac but when we don’t have it hot wired and we just try the relay it does not turn on we tested the relay and it click on and off but could it still be faulty and also could it be that the power ground wire from the ecu to the relay has a short and not giving it the power it need to fully turn on and make the fan run
