i had the same problem about 2yrs ago with mine. i took her up to the mazda dealer and they fixed her in like two hours and to a bill of $120. and i do belive it was a resistor, but on mine only the speeds 3&4 worked if i remeber right. i found somewhere on the internet that this was a common problem on our cars.

is it just your heater? b/c nothing worked on mine in those speeds. no a/c, no vent, no nothing. and i belive it was $120 for everything.
