You didn't say what year but my 2002 S10 Blazer has the HVAC blower motor resistor located under the hood, on the firewall, passenger side, close to the blower motor. Unplug the wire harness and remove the two small screws holding it in place and gently pull it out.
The fuse. The blower motor speed resistor. The blower motor relay. The blower motor switch. Check for power at the blower motor connection.

The blower motor speed resistor is burned out. You can replace only the resistor but the resistor probably burned out because the blower motor is going bad. If you want to fix it for good, replace both the blower motor and blower motor speed resistor.
Under the hood, on the firewall, passenger side, close to the blower motor.
Check to see if you are getting power to blower motor - if so replace blower motor If not check fuse, switch, resistor pack.
Should be behind the glove box. The blower motor speed resistor is located under the hood, on the firewall, passenger side, close to the blower motor.
The blower resistor gets overheated and burns out usually because the blower motor is failing also.
Check to see if you have 12 volts at the blower motor. If yes then the blower motor is bad. If no, then the resistor, relay, or fuse is bad.
They get noisy, squeal and vibrate. Also if you keep burning out the blower motor resistor, that is a sign the blower motor is on its way out.
To replace a blower motor on the resistor first you take off the nozzle and then you go into the motor through the nozzle and unlock it then repeat and oil and done.
