This has happened twice in the last week, I have a 99 GMC Burb with the GM security system. It would quit running and the little chirp for the security system would just go on and on forever, the truck seems like it has a dead battery, no lights, windows, locks, etc won't work. I've owned this truck for 2 years so I know how to start it and wait etc for the security system, so it's not an operator error, ok? Anyway, after a little while, it would start right up like nothing happened, no jumping needed. Anyone had this problem with this security system before? SWMBO got stranded today while I was golfing in her Jeep, so I really need to try and fix this one . TIA.
