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.
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?
