SPDrift Posted January 11 Report Share Posted January 11 Hi All, Having issues with getting my a/c to work in my s15 - manual climate control unit and the a/c button does not light up. SR20, Link G4X NS15X ECU I am a a/c noob so don't understand how the system works entirely but so far I have been able to do some diagnosing. 12V at climate control unit, 12V at aircon switch, 12V on pin 11 on ecu but no voltage at pin 41. Also, the thermo control amplifier does not have 12V also. I am not sure where to look next and was not sure if pin 41 should have 12v? Any help would be appreciated Quote Link to comment Share on other sites More sharing options...
