If the blower works on the defrost mode only, you could have a disconnected vacuum supply line coming from the engine. If the blower motor doesn't work on any mode or speed you could have a blown fuse, burned out blower motor speed resistor, bad switch or a bad blower motor.

Why does the ACHeater blower only run on high in your '96 Chevy Cavalier?
Blower motor resistor is bad. It is a little circuit board with resistors on it that changes voltage to the blower motor. When it goes bad, you get full speed only.
How do you fix a blower fan that only works on high I have a 2002 Chevy Impala?
You need to replace the resistor board locate on the inside passanger side where the blower motor is located . It is attached to the blower motor with 4 screws as I recall and can be readily replace if you are somewhat handy around cars. The part Iam sure must be purchased at the dealer for around 35 dollars.
Where do you find the 01 Chevy Venture blower fan resistor for the high setting and how do you replace it?
Hi, The Blower Motor Resistor pack is mounted right next to the blower motor. You have to remove the insulator panel from the passenger side floor board area to get to the blower motor and the resistor pack. Once you have that off, the resistors and blower motor are near the firewall, and can be removed by taking out the screws that hold them in place. I believe there are 3 or 4 screws that hold the motor and 2 screws for the resistor pack. There should be a "Related Link" at the left of this answer that will give you more details.
