It could be the resister on the blower motor as was mentioned in the other post, but it'll usually go out completely for particular fan speeds. Unlikely to cut in and out with the rpm of the engine.
My truck would blow at certain speeds for a while and then they all stopped working. You could barely feel the A/C when idling but it would blow a little more when driving. When I pulled the resistor I found that the connector that goes to the blower motor had melted. I changed both and I'm back in business. Changing the resistor was really easy, but rewiring that connector sucked donkey balls.
