If it does not work at all, it is probably the blower motor. Easiest way to check it is with a test light (cheap at the parts store), if you have power to it and it doesn't work then replace it. It will be dim at low speeds so be sure to check it at all speeds to be sure.
It could be the switch but it isn't likely, test the motor first, then you'll have to pull the switch and look into and out of it.
If it only works on high then you have a bad blower resistor, this is what determines the speed of the blower by regulating voltage, it is bypassed on high so you get maximum blower output, so its an easy diagnosis Arnold, replace your blower resistor, it screws into the heater box and has a plug going into it.
The knobs just pull off, although they are a pain sometimes.
I have a wiring diagram for the switch/resistor/motor on my website MaverickGrabber.com, click on 'Technical Info' and then 'Wiring Diagrams', its Diagram 5. -CP
Don't know for sure,but mine only works on one speed,...wideass open!Cooks you after a while.Every once and awhile it won't work at all unless I play with the switch.Play around with your switch and see if it comes on.If any body knows how to get the little knobs off of the switches please let me know so I can replace it with a "new" one.Thanks.
