Does the fan work when you switch the fan to high? The fan switches are known to go bad on these. Does the fan switch feel loose or sloppy? Do you need a wiring diagram?
Click the links below for the component locater and the wiring diagram. The blower and the resistor are the other 2 most common failures. If it works on high then it is not the blower motor because it bypasses the resistor on hi. Pull the front air scoop under the hood and make sure the recirc/fresh air door is set to fresh. You can reach in there and give the squirrel cage a spin and see if the blower starts to work while the switch is on. Sometimes if you jar it will start to work in which case the blower motor will need to be replaced. Do this before we get into allot of ohm checking.
Let me know.
