I have a 2007 GMC Sierra 1500 (new body style). Just the other day my front directionals and my rear reverse lights/brake lights won’t shut off. The front dims slightly when in park/shut off. My reverse lights also stay on while driving. This is a relatively new problem. Something weird that happened that I think may have started the problems is that the other day when I turned the key off and took it out my truck kept running for about 15 seconds afterwards then shut off by itself. I didn’t think too much about it until I go inside for about 15 minutes and I saw those lights were still on. It’s 2 days after and the lights are still acting up. Any ideas?
