Mine was down to 2 speeds, I lost the low speed which is the one I used most. The problem was a resistor that only cost (believe it or not) $15 from the dealer.
The high speed is the only one that doesn't use the resistor so it is possible your problem is a fuse. If the blower motor fuse is OK, while you have the glove compartart out, follow the wiring harness down to the right, as viewed throught the glove comppartment opening, I think the resistor is in that area.
