If you have no speeds at all, including high speed and you have power at the fuse and the fuse is good, I would suspect the heater blower speed switch and or the electrical plug to the switch is cooked. If you have high speed only and the rest are dead, I would suspect the blower motor speed resistor.
What else can I help you with?

It's right behind the glove box. However you must be sure that it is not he fuse or the blower motor resistor that has gone out on you first. You can test the blower motor with 12V power as that is what it gets on high speed. www.trailvoy.com Trailblazer enthusiasts forum.
