Hello everybody, i was installing aftermarket stereo and tried to connect a harness (that was not the right harness as i understood after) on my 2005 TL, i may have connected this wire i was not really suppose to connect (illumination orange wire), i am not sure if this is the reason for my climate control to start malfunctioning. I seem to have power coming because screen turns on but there is no information displayed, no buttons work except rear windshield defrost. My fan is working on full speed with ac on with no control from the climate control unit, buttons don't do anything. I have tried to change blower resistor and have checked fuses. Removed positive from the battery and put it back on. Nothing. Also my VSA light is on, it was not the case before this aftermarket stereo install Does anybody have any idea why this is happening? What is the solution? Please help!
