There is a small switch on the dash below the fog lite switch that has an "I" and an "O" on it. I can't seem to find out what it does. Does anyone know or have something similiar? It looks like a factory switch and is only like 3/8 wide by about 1 inch high, and is a rocker switch. Thanks all. | | | | | Joined: Jul 2004 Posts: 5,708 'Bolter | | 'Bolter Joined: Jul 2004 Posts: 5,708 | acmegarage,
That's the 'belly-button' switch...
"I"= inney
"O"= outey
Could it possibly be a button IN/OUT for 4WD or Quadratrack?...a non-installed option on your truck!

The description sounds like a typical appliance switch; 1 for on, 0 for off. | | | | | Joined: May 2001 Posts: 7,438 Extreme Gabster | | Extreme Gabster Joined: May 2001 Posts: 7,438 | From the main page of "General Truck Talk" Please, no flaming, advertising or anything else not directly related to the care, restoration, preservation or use of old GM trucks!
