I have a strange intermittent electrical problem in my 2010 Colorado. On cold days (say below 15 degrees F) after running for a few minutes I get warning lights for just about everything (ABS, brake, Traction control, TPM, etc.) and the following things stop working: turn signals, wipers, windows, heater fan, and maybe some other stuff. However the truck continues to run just fine. If I stop, turn the engine off and then start again all is back to normal. Usually if I drive long enough the things will come back to life, but I really can't drive far with no turn signals, wipers, or windows. I have an almost-new battery, and I have cleaned the various grounding points including the ones on the sides of the engine compartment. I took it to a dealer, but they were not able to reproduce the problem, probably because it wasn't cold enough, and they had no advice for me other than to bring it back when it happens again, which is not easy. Anyone out there have advice on this?
