Here we have a good used glow plug control module removed from a 2011 Duramax 2500hd with the LML engine, will fit all 11-14 sierra 2500hd and 3500hd with the LML Duramax engine and maybe even other years but I'm not sure. Please ensure this will work for your application by viewing all of the photos, these are non returnable. Any question please just inquire.
