If all other speeds work then it is very possible you need a blower motor resistor. ASE master tech. ROB ADAIR

I only get the fan to work on high speed, the lower speeds do not work

The Blower Motor Resistor also called Manual Temp. Control resistor), is fried, replace. The price with floor console $25 and without floor console $65. here is a pic.

the resistor is located on the blower motor housing, fastened by two screws. It is the part where the electrical plug connects, the plug on the pic. goes to the blower motor.
A HELPFUL - 4 THUMBS rating for this solution would be greatly appreciated. Thank you for using FixYa.

Blower only works on 4

That is the high speed right? That means your resistor network is burned out. The resistors lower the voltage to the motor. Better info available through repair manuals

Heater blower

Sounds like the blower motor resistor is bad. These things go bad all the time. and for the switching modes there is a vacuum line that runs under the window in the engine compartment and runs by the alternator, its tiny and may take a few minutes to find. check first by the evaporator case and follow it by the alternator to the driverside of the throttle body. these too break and will not allow the heater mode changes. the blower motor resistor controls the fan speeds and the vacuum line allows which vent the air flow goes through.
