hello i bought a used maxima 09 but it came without a radio so i changed the car radio to touch screen and the ac controls wont come up.the conditioning controls does not light up but the new radio is working,please i have tried changing relays but the best i go was just the fans coming up.please i need assistance with solution on what to do.

 

Did the AC controls work before you installed the new radio? Just trying to figure out if the AC controls are part of the stock radio.

 

No the control was not working before i installed the radio and the dashboard monitor does not comes on.but after installing the radio the revers camera works fine on the new radio just the air conditioning system controls that does not comes on
