I have an 02 LS, 3.4 liter, over the summer I was having a problem, the security light on the dash monitor would come on and a clicking noise was comming from the dash, this went on for a while then with the security light on and clicking going on the headlights would go from daylight to night power repeatedly, and while this was going on the ac would cut out, it only seemed to do this on hotter days, it has cooled down and has stopped doing it, the security light is out but now when I leave the car unlocked and get into it the dome light flickers a couple of times, when it's locked and I unlock it to get in it dosen't do it, and every once in a while it will keep me locked in when I go from drive to park. I have already took it by the dealership and they can't find anything wrong with it as it wasn't doing anything when I brought it by which means that the computer didn't record the security light comming on. Any GM techs out there willing to help a guy out?

Are you sure a code wasn't stored, maybe in the BCM instead of the PCM? It sure sounds like you have a voltage drop issue to me. These cars had huge problems with a resistance inside the ignition switch which would store false security codes and at times not let you start the motor. I'm not sure about the lights jumping back and forth, but if you had a voltage drop, the relay might be dropping out which would send the car back to DRL. Intermittent problems are tough and irritating for everyone. If you don't have any aftermarket crap wired in, I would suspect the ignition switch.
