Wait a minute... The switch lights up fine, what doesn't light up is the actual dash indicator in the instrument panel where the gauges are when I hit the switch...
Any difference there???
OK, just to be clear here, there's a possibility of TWO lights on the switch: 1) a little LED indicator light that toggles on and off with the fog lights; 2) a backlight that lights the icon on the switch when it's dark out.
If you are saying that your car does indeed have light #1
and that lights when you toggle the switch, then the switch is fine! The indicator LED (#1
) power is supplied from the BCM, so the BCM is definitely getting the signal from the switch just fine. Note: I'm not sure if all, or some, or no, Skys have the LED indicator (#1
) on the switch. I CAN tell you my Solstice has it though
If you are only saying light #2
works (the backlight) then nothing is determined as to where the issue lies.
There's four pins on the switch so....maybe.... one set does the grounding thing for the BCM and the other set may complete the circuit for the light
One pin is ground (common); one pin is the switch signal; one pin is for the backlight +v; one pin is for the LED indicator +v (if you have it). Total, 4 pins.
