Speedy, for a guy who seems to know everything, I can't believe you don't know this one... Generally speaking, when blower motor speeds don't work in GM vehicles, it's usually the blower motor resistor card, down by the blower motor.

and the resistor card is located where?

like I said, right beside the blower motor...the blower motor is located under the glove box on the passenger side, remove the trim cover/interior light first!
