I have a 1999 K1500 truck that is having a very odd problem. Last week, I was on the road and stopped to get gas. When I turned off the ignition key, the truck continued to run, but all of the dash lights went off and the Check Engine light came on. Also, once the ignition key was off, the truck was idling so low that I could hardly tell it was running. When I went to turn the ignition back on, the check engine light went off and the AC blower fan came back on. In addition to the truck still running when the key is off and out of the ignition, I also lost all of my trailer lights and parking lights. My turn signals, brake lights, and hazzard lights still function properly. My first thought on this problem was that a relay is hanging up; however, I am not sure where to even start looking for which relay it might be. Any help would be sincerely appreciated.
