I have a 2003 gmc sierra with 175,000 miles and my vents no longer blow air, was working fine this morning a/c felt great then i went for another drive and it no longer worked, think ive been hearing strange sounds under my dash for a few months im thinking it might be my blower motor

Yeah the blower motor would be my guess as well. You may want to change the resistor while you are at it, but if that goes, it normally will still work on high.
@nlord recently fixed my issue couple weeks ago, was a wiring issue where the blower motor and the resistor connects, turns out the connection to it melted and corroded so i just replaced the wire and the connection and works like new
