Not sure if I have this in the wrong section, but I apologize if I do.
I have an '09 Tahoe LT and over the last few days I have been having some quirky electrical issues. There's times where the truck wont even start but if I keep trying or give it a few minutes it starts up fine. There are other times where I see the overhead lights pop on and think that it'll start and it doesn't, but the radio will come on and all of the dash stuff. Another time, when I was on the highway and put the cruise control on, it wouldn't stay on very long and then all of the sudden I could see the speed dropping down because cruise was turned off. That happened 3 times in about 5-10 minute period. Another incident I thought one of the back windows was down just a hair and so I pulled up on both window buttons on my door to close them and the radio went off, not sure if I had cruise on or not that time. On that note, there's been a few times where the radio just randomly turns off and back on.
None of this makes sense to me and only recently started. I disconnected my lights I installed under the hood to make sure that wasn't an issue, and the behavior continues. I have a cheap OBD II reader that I use just to read and delete codes and it didn't see any codes. I also had On-Star run a diagnostic and they didn't see anything either. Just for good measure, I had my battery and alternator tested, and both came back as being good. Has anyone else experienced this? Is there anything I can do to troubleshoot more than I have? Any help is much appreciated.
