I finally figured out how to turn off your automatic lights and light sensor! Press your dome override button twice

 

Nevermind. I guess this was already figured out in another thread....to think-I even did a search! lol

 

Or you could install a resistor (I'd have to look it up for the correct one but found at Radio Shack very cheap) in place of the sensor.

 

Just one more reason to get a copy of the owner's manual for your vehicle. I've seen so many questions here that are answered in them.

 

I looked a few different times in my owners manual, and I didn't see it in there. If you just so happen to have a copy of the 2004 blazer owners manual layin around, see if you can find it? If so, I'd be intersted in what page #.

 

Nope, don't have one since mine is a 2002, but in that OM it's on page 2-57 (Section 2 Features and Controls, page 57) under 'Daytime Running Lamps.
