We just picked up a 2010 Suburban 2500 LT. It has factory foglights, but I have NO clue how to make them turn on! I know where the switch should be (left of the steering wheel, next to the headlight switch) it’s not there. They don’t come on with the running lights, and I’ve made sure my hi-beams weren’t on. Anybody have any ideas? I know I can probably just change the switch, but before I do, I wanted some of your thoughts. Everything else is OEM, it seems odd the previous owner (it was a fleet vehicle) would put the wrong switch module in. All else fails, I’ll talk to a dealer.

 

I have a 2008 2500 LT - the fog light switch is the lower half of the rectangle surrounding the panel dimmer switch. In between the headlight **** and transfer case ****.

If the switch isn't there, you'll need to crack open the dash and install a new one and connect the proper wires.
