I'm pulling fuses for my on-board computer and cruise control to see if any are blown.

Why? Because my cruise control is non-functioning and my OBC won't tell me my average speed or average fuel consumption, and my limiter doesn't chime or anything when I exceed it.

So this is what I'll be doing tomorrow at school, and if this fails I have no idea what else to do. I'd like for this stuff to actually work, especially my average MPGs and cruise control.
