Fog light switch is not wired correctly

[99_Yukon]

So I picked up a fog light switch from a member on here and installed it into my Yukon. I hooked up the wiring to the back of it an for fun just turned it on. Well it turned on my rear blower motor. So that's not what I wanted it for? How do I fix this and get some wires up to the front for fog lights like it should be?

White, grey, red and blue.

I just plugged in what was there behind the dash.

those colors don't correspond with the service manual. some anyway


brown, purple, gray, yellow, and black is what is shown for the fog switch.

will research those you posted tho.

Thanks. I guess I'm more concerned about how to get the fog lights wired up correctly now. I wanted to add the limited style bumper with fogs and have it work like from the factory. Is this going to be possible?

not find a hvac connector yet with all for colors you listed yet. only three and they indicate front control of rear blower. black instead of gray will keep looking.

if not originally equipped the wire provisions will not be complete so you may need to add some wire routes. does the fog relay socket have all the terminals in place?
