I have an 05 Trailblazer and have recently started seeing some issues. About two weeks ago my clock kept resetting to 12:00 about 80% of the time. Sometimes it will maintain the time overnight while other times I turn it off for a couple of minutes and it will reset to 12:00 again. I have also had some intermittent issues with the rear wiper cycling once shortly after starting my Trailblazer and then two days ago head lights started acting up. When switching from High Beam to Low Beam there is about a two second pause before the Low Beam comes on. Just seems weird for all these to start happening around the same time individually? From what I can tell the Low Beam issue may be the relay but does this relay effect the rear wipers and clock? Or possibly and ignition switch going out? Any ideas would be appreciated.
