Computer code for fog lamps

Mike Ryffel · March 2, 2020

Just had my local dealer install factory fog lamps on my 2020 sierra. After they were installed was told they dont have the computer code to activate it. Now I have installed fog lamps but they dont turn on. Am I out of luck or is this something my dealer should have?

Were they purchased as a GM accessory kit? If so, the kit should have come with an activation code.

Dealer installed them knowing they wouldn't be able to get them to work???? Wow what BS. Is this their first fog install? That's a sorry service dept....

I bought the GM fog lights from the dealer and installed everything except the jumper wire into the underhood fuse box, took it in today to have it programed and finish the wiring, I lost the sheet with the code, but still had the box they came in (serial number is on the side of the box) the tech was able to call GM help line with the serial number and the help line gave him the code. $131.00

Thanks for the info. The dealer installed everything except the codes. To lazy to follow up to get the codes. I have them now and hopefully my back up dealer will program them tomorrow. Moral of the story is sometimes service advisors are either lazy or incompetent.

Jeez that is a sad story but I guess all dealership service teams have a bad day now and then.

I had the same situation happen to me. I installed the entire fog light kit myself (correctly) with the help of the GM instructions a friend game me. Obviously the lights didn’t work because the had to be programed. I brought it to the dealer (Rydell) two days ago for service. They took a look at it, gave me a call later in the day asking for the serial number or number on the sheet (which I was never told to keep.... should have kept it) that came in the box... I was at work and couldn’t remember where I put the sheet. I asked for options and they told me there aren’t any besides BUYING A WHOLE

NEW FOR LIGHT KIT FROM THEM! There has GOT to be a way they can track down my order and connect the dots. I’m pissed. Anyone have any suggestions???
