My 2003 is has a blower that will only work and high and the AC compressor will not engage. This problem came all at once. Where and what do I need to look to find out how to getting is to work again.

Fan speed is a common problem...blower motor resistor which is located on the firewall behind the egr valve. It's the little black box. When was the last time you ran your air cond?
Compressor not running could be because you may be low on freon. Quick check is to jump the low pressure switch

It's actually called the BCM, Blower Control Module.. As said,passengr side on fire wall near cam cover. You can do a a little test but turning car on and A/C on and then give it a good rap with like the handle part of a screw driver. If the A/C now works, then that s your problem..
Link to fix it yourself if that is the problem.

No, the BCM is not in the compressor circuit. It sound like there are 2 separate issues.
