I have a 99 Denali and having some problems.
1. When i start the truck the headlights auto come on, all the time no matter how much sunshine. DRL's do not come on...niether does the DRL light on the panel. Is it a relay or what? If so, where is this relay?
2. When i stop at a light or sign....then go to take off i get a clunk thud type noise feeling from the rear and a chirp sound. Only when i take off. What is that and how to i fix it?
This site is pretty cool, went to a GMC site and there wasnt much activity on it at all. Any help would be nice, thankssssss
