Yeah, it's the resistor. Go steal one from a junkyard, the stealership gets alot for them. It screws in underneath the glove box on the passnger side like sergio said. The reason 4 works and 123 don't is because the resistor steps the voltage down for teh lower speeds, but on 4, the high setting, the motor gets fulll voltage, so it doesn't pass through the resistor, it goes straight from the switch to the motor. If you can't find one at a junkyard let me know, I've got one I'll sell you.

I'm not sure why they go bad, they just do, it's a common problem though. I don't know what they cost new, upwards of $30 IIRC, you'll have to call a $tealership and ask. You can always check with Greg Vogel at www.mossyperformance.com Although he might not be much cheaper than a local dealership, if the dealership has to order it anyways, greg will ship it to your door.
