A couple of things:
Some community colleges offer an inexpensive way to get into a 4-year state university program for anything. Go to the CC for two years at their cost and if your grades are good enough, you can get into the local Enormous State University. I live in Maryland, and anyone that goes to the county community college can get into the University of Maryland this way. You aren’t guaranteed housing, but you can get a UM degree that is every bit as good as any other. Maybe Illinois has the same deal. I am not saying that you shouldn’t look at a career in auto repair, just that there are other options that might appeal to you.
School doesn’t necessarily make you good at anything. I have an engineering degree, and the thing it gave me is a way of solving problems. I certainly wasn’t good at solving problems, but it was a start. I developed my problem solving skills over the next few years, and I continue to learn better ways of approaching problems after 45 years working.
Whatever you decide, just recognize that you can always change your mind. You are young and have a lot of time to recover from a little time looking for the right career. My daughter didn’t recognize that, and had a lot of problems switching to something she really loves.
