SOURCE: heater blower motor
the heater blower motor is located undr the glovebox there are 3 small bolts holding it in place, 7/32 socket i believe after loosening these you will most likely have to move the wirring harness that goes through the floor to get the motor to drop down. after the you get the motor to drop down there is a large vaccum line that goes into the side of the motor gently pull this out be careful not to pull the other end of the vaccum line loose from inside the car. the is a power plug in the side of the motor that u will need to unplug to free up the blower. because it is hard to see the power plug needs to be pressed down on the top and pulled simaltaniously.

Try replacing the blower motor resistor, it has different resistances for each speed. Mounted on the passenger side air duct, it is kind of a ***** to get to but you can see the harness if you invert and shove your head up into the footwell.

It is behind and underneath the glove box back by the firewall. No need to pull out the glovebox.You may need to pull the carpet back to get to one of the bolts.

assuming you know where your blower motor is you can check the motor for power with the switch on and see if you have battery voltage at the connector. if you do then it is a bad blower motor. Most of the time when a resistor goes out it will work on high only but no other settings. with it not working at all seems to be motor. Hope this is helpful.
