Kinda new here need a lil help.

[Towman3500]

On so I just bought an 08 3500 that is a auto load tow truck. Yea a repo style truck. Well as I'm going thru it and getting a list made up of oil things to fix I noticed that I have no head lights at all in any spot on the switch. Also I have fog lights but can't find where to turn them on at. Am I missing something here? I own a 97 a 96 and a 99 chevy truck but those are easy compared to this thing. Any help would be great thanks

There is a button below the light dimmer for fog lights, it doesn't look like a normal switch but push it in....not sure about the headlights but to turn the knob...hope it helps. Ski
