running lights

GREAT question, I would like to do this too ... why don't people reply to these forums?

For the Envoy, press the DTR light button 4 times, the headlights go off. Turn on the foglights by pressing their button. Done.

Are your night time back lights automatically come on or is there a button you have to press? My brake lights work but the other lights don't please help

I see sam's ans says to hit the dtrl button 4 times. One problem. My 03 envoy doesnot come equip with a push button dtrl button. Mine is rotary headlight switch which can turn headlights and fog lights off but all lights come back on soon I turn fog lights on. I want to use fog lights only. How do I accomplish that?
