My wife's brother has a 2002ish Chevy Trailblazer (total POS) that is having a weird set of problems. For the last couple of weeks, his hvac fan hasn't worked at all. There is heat, but it just won't blow out. The car also won't let him shift from 2wd into 4wd. I suggested maybe fuses, but it seems weird the fan thing comes and goes, and the 4wd thing may as well due to the rarely-used nature of that option.

Does anyone have any suggestions on where to start on this?

Thanks in advance!
