So I got a new battery in my car about two and a half weeks ago now, and since then ( as you can obviously see above) my odo and trip computer won't work and I'm not sure why. Before anyone thinks the guy that changed it did something wrong, he didn't. It was a simple unscrew the connectors, take the battery out,red crew connectors and drive off. Since the day I left the trip computer and odo won't read. I get my odo readings from OnStar who keep track of it apparently. So anyone knows what could have gone wrong?
