i replaced the factory Fog Light switch with a lit Contura that has the on indicator as well. I got all of the other switches to light up when switched on.... but the factory fog light switch won't light up with 'on' indicator. I didnt replace any wiring from the factory fog switch, just added what was needed for dash dimmer etc. Wired it the same as all the other switches, it just wont light up when on. Lights up fine with dash lights.
i checked the ground its good, its not jumpered off the dash light ground feed. I can't figure out why it won't light up when flipped on.
