I replaced the battery in my 2018 Chevrolet Silverado this morning. Once I got it all back together, there were no issues that were apparent, then I got in and drove off. When I reached the first part of my drive where I needed to use my blinker, it came on like normal, flashed about 3 times and then started rapidly blinking and gave me a "rear turn signal failure" message. It did the same for both left and right side. The blinkers were both working when I got out and checked, but they were flashing rapidly. What in the world could have happened just from changing the battery? Any help or ideas is appreciated, thanks in advance!
