Adding Fog lights, will it require a bcm reprogram?
As the title states, I'm reading how simple the "stock" fogs are to install, but apparently you will or may need the bcm to be programmed to run them? Can anyone verify? Here's my thought. I want to run a rigid light bar in my lower grill, and attach it to the factory fog light button (that I don't have and will install) and put my rigid light wiring in the factory fuse box to run it without splicing the harness or adding an aftermarket button drilled in somewhere.
So so back to the main question, what will you need to do to use the factory button in the factory fuse box and will the bcm be cool with it, or how do I make it all happy and working?

If you know anything about electrical on a car, this is an easy one. If you don't, it's still easy. To find out if your bcm needs the flash or not, open up the fuse panel under the hood.Locate the fog lamp fuse (can't remember which one it is but it isn't hard to find). Take any 12v light or a test light and connect one side of the light to top of the fuse (one of the two exposed metal parts on top) and then the other lead of the light to any nearest body ground source. If the light lights, you're good. If not, you will need a flash.
Just called Berger Chevrolet in Grand Rapids, they said its manufacture date is 9/11 and will likely need to be reprogrammed. They said the kit is $230 and install around $60 (including reflash?) but all I really wanted was the factory button to give me power in the correct fuse, not really needing the gm stuff past the fuse box. Kind of at a loss, $100 to turn on a bcm button
You can still verify wether or not you need to reprogram it without the button. That circuit is live regardless if it's turned on via the interior button or not. honestly the best route to go if you are trying to save money and have decent fogs is to get the set off eBay for $49.99. Many users have them and best of all you can get them easily replaced for free of you run into any issues because this is just how the games goes on eBay. The sellers of these accessories will get afraid of getting negative feedback and will send you free replacements while letting you keep the new ones. This is what happened to me. I wasn't pleased with one little thing and now I have 2 kits for just 49.99. Many users on here have those same kits.one of the names the kit goes under on Amazon and eBay is Spider Auto. Then you can easily find the factory plug and play switch on eBay or at a junk yard. I found mine on eBay from a junkyard that sells parts online for about. So you can give yourself a 100 percent factory installation for less than $100, not even.

Can you explain how that works? If it's like the high-beam circuit I looked up, the fuse won't have power until the fog light relay is on. And that won't happen until you push the fog light button. If the fuse is before the relay, it would have power all the time - unless you're saying there's a fusebox modification that goes along with the reflash.
I do believe I had the switch before I tested it. I went out just now to verify and you do have to have it on via the interior switch first. i guess in my case I was just so anxious to get the fog lights that I ordered the switch first before the serperate $49.99 kit because if none of it worked I knew I could return it all hassle free. The only switch plus eBay fogs are a killer combination. You can even find an 18-20 gauge wire terminal so you can actually install it into the backside of the fuse box instead of using an add a fuse, making it just like factory. No way am I paying close to 400 for some fog lights. These dealerships are crazy.

Ah, that makes sense. You were testing before pulling the trigger on the more expensive part.

Use this for your wiring. Made my driving lights install easy. Make sure to run the ground wire through that circle sensor that all other grounds run through too.

Check out ebay for deals on factory fogs. You may have to check often but I got mine for $120 shipped (I have seen them go for cheaper) Use these numbers 95248415, 95903470 and 96983696. Check the box for "include description" when searching. Don't be afraid to make offers if they best offer listed. The person had mine listed for $175. I got them down to $105.

I have a 2014 cruze 2lt and I had my installer put in some LED foglights direct to the daytime running lights, they worked good until 1 night they stayed on ALL NIGHT! I could not get them to turn off and didn't have the space or tools to see what could be causing it. As of now they don't turn on anymore, could it be that it blew a fuse? or what would cause them to stay on all night and then not turn on again?

Link above if they really needed it for update. Only the 13's listed in the link needed to be turned on.
