The front heater does not work, the rear heater works on high and not on low or med.
Your resistor is burned out that is why you only get high speed. Also the front blower motor is out. But check the wiring going to the resistor and make sure it is not burnt, if it is it also has to be replaced. Just went through the same issues.

Hi ,The resistor is in the heater box located under the dash on the passenger side.It can be seen when you crawl under the dash and look up. It has two or three bolts on it. It will also have a plug connected to it, which has to be disconected.

I had the same thing happpen with mine. The unit is located behind the glove box and is just left of the fan held in place with two screws. I bought a new resistor from radio shack and installed it in the unit.

I had the same problem, I changed the resistor that is located behind the glove compartment and it is all good now. That resistor doesn't look like a resistor when you look at it. To reconise this item, there are two connector attached to it, the one from the blower motor on which there is a green wire and a black wire. The other connector attached to the same resistor consist of 4 wires of diff colors.
