There's a TSB (technical service bulletin) from GM that says to replace the blower motor resister and the pigtail wiring due to internal melting due to heat. Go to a GM dealer for a copy of the bulletin, it'll give you the part numbers to purchase.
The blower and resistor are under the dash, passenger side, behind the glove box, near the floor. It's a tight fit to get the bolts out and back in, oh yeah, special tools are required.
