I know there is only one Thermistor or (thermofuse) to change. On my jetta
the only speed on the blower that would work was 4 after i changed the
thermofuse they all worked, i beleive that the resistor is in series before
the circuit splits. I didnt have time to make it to radio shack on
lunch....... it seems there are a lot of broken car stereos out there to fix
so i will go either later tonight or tomorrow.
