Try switching your wall thermostat fan switch to the "on" position. That is suppose to make your fan run 24/7. If it starts then your stat is not always making the connection in the "auto position, and you need a new stat. If it still won't work, remove the cover of your furnace and trying spinning the motor by hand(w/ switch back in "on"). If it starts then you either have a dead spot in your motor windings, or a bad motor start capactior. If the motor is old your better off just replacing both. Unfortunately you can't go and get a motor just anywhere, but you can get a stat at a hardware store. If you need a motor check on the furnace manufacure's website for a parts dealer in your area.

Most likely is the blower motor resistor has burnt out. I have an AMP meter to check if the motor is drawing to much power then I replace the resistor. Located under the glove box right next to the blower motor 2 screws.

Sounds like the switch to me, too. I have the same problem on my '62 Chev Pickup. If nothing was happening at all, I'd say to check both the switch and the motor.

possibly the switch but i would change the blower resister its located on the fire wall or near the blower fan .most of the time that is what it is. it will have several metal coils and 1 or 2 of them are broken or rusty that's why you loose some speeds.
