Hey
So I was installing a new audio headunit in my 2003 Sentra, I couldn't find a wiring harness so I cut mine, and when I cut it the illumination wire touched a ground the lights in the car went on for a second and turned off. I thought nothing of it and finished my install of the headunit. Then a few hours later I went to drive the car and the illumintaion didnt work. I think the dimmer switch is burn't (I checked all the fuses and all are ok). But now on the dimmer switch there are three wires, the yellow/red has 12v when the lights are on, the green/red has 12v when the light are on and the black is ground. It doesn't make sense to me that both wires have voltage, is this right can anyone verify. Also the dimmer switch has resistance in it but it doesn't change when the knob is moved.
