The short answer - you may. Some cars haven't needed it, some do. I don't recall if there's a pattern to figure out where you fall.
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.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.
They told you that?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
Yeah when I told them the last 8 of the vin, that's what they said. Just checked the body sticker in the door and that's accurate. So there's no way to get around the bcm calibration then, huh...
Just called another dealer and got "I don't think that's even possible." Uhhhh, I can give you website links and show you it is, I just need some help on the bcm program. *office space voice* "yeah, ummm, let me call you back if my tech says we can do it". Ok, thanks guy lol
