Chevrolet Blazer Repair Question
Go and open the hood and unplug the blower motor hot wire at the plug of the blower motor located on the passenger side of the car at the firewall. Get yourself a automotive test light (they are cheap) and ground the wire from your test light and put the opposite end to the hot wire going to the blower motor. Make sure your your key is in the on position or have the car running. If the test light lights up you have power going to the blower motor and the fan should be working, if not you have a defective blower motor. If no power at that hot wire it may just be the switch. I have found that the majority of the time the blower motor is bad. If the switch only works on one speed the heater resistor is bad. Hope I answered your question. Good Luck!
