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???

      I trust you saw the other comment where he knew what he was talking about !. Yes, these darned newer vehicles with all their so smart they are stupid technology, goes and drains the battery down. As you might see my other comment, I installed a Noco 5 battery tender under the hood and at this point still have the cord routed so I have to lift the hood and then plug it in but am typically parked in a garage or a shed so its not risking the engine hood in the wind. That way I am assured or hopefully so of not finding I have a battery drawn down and can't even start the truck and that also damages the battery to draw it down too far.

      I guess no surprise my guesses were wrong !, at least now I know if I ever happen to see it grayed out in my own truck as to what is going on.    I never happened to catch my truck with it grayed out, it seemed every time I would test to see if there was an update it never found anything and yet more than once I would check to see if there was an update and there was nothing, then a day later or even that same morning I would drive to town and after more than one engine shut down in town as I did my errands it would pop up that there is an update now ready to install and the only place I have a connection to the internet is at home by wifi so its not as if it grabbed the download while driving. I don't trust these new vehicles due to all the crap they can decide to do while sitting for some days not running and run the battery down so most of the time if I know the truck will sit for a few days I plug in the battery tender I have mounted under the hood and so the only time the truck must have downloaded software was when it was sitting in the garage where the signal is awful but I have that tender plugged in and somehow it managed to download it. I honestly detest all this crap, way to easy to leave a person stranded.    Since I don't trust any of it I don't do the install of the already downloaded software until I get home and sometimes have even sat in the truck to watch what its doing as its going through the process to its conclusion as its not like it is set up that it will tell you the next time you fire up the engine that the update that was initialed actually installed or installed properly. Yes I can go into the updates and see the list. After I go through the install where I feel its safe to do so in case it breaks down as a result, I will plug in the battery tender after the fact to recharge as I don't know how much power its taking just to do the install and that can take a while for it to install.

      Thanks for the reply. All settings were correct and the engine was off, as it was supposed to be. It turned out to be something simple. I took a drive for about an hour. I must have had a low battery without knowing it. The voltage gauge on the display looked ok. At the end of my drive, I shut off the engine and the update prompt came up and it updated normally. It’s ironic because one of the features of the update is a reduction of battery drain.

      when it's greyed out that is it's way of telling you that it's downloading the patch in the background. Eventually it will be fully downloaded and then it will prompt you at ignition shut down to run the update. I highly recommend doing the update once you get home and can run it a few times. I've had several issues with updates not going the first time around and I had to retry the update multiple times in my driveway before it was successful.   Some updates are huge and take awhile to download. You can help it by connecting to your home WiFi and keep the truck on service mode for the ignition and keep it alive for awhile on a battery charger too. There are specs it needs to be in for updating such as a full enough battery charge, no running ignition, etc.

      I am not techy at all but wondered if you have the truck running but sitting still in park as some functions gray out as soon as the truck is moving. I believe in the settings for updates you can choose for it NOT to update and I wonder by chance if maybe that was chosen before and now it won't allow you to chose to press update, I think that is back in the settings menu where it has all the items one wants on or off etc. Also I assume you have a wifi connection and checked that it has some signal strength, not that it would have anything to do with the grayed out updates choice in that case. What I am thinking out loud of here may be be of no value but thought I would suggest it, sometimes it can be the simplest thing that resolves an issue.
