Question about 2001 Mazda Protege
I just had my alternator replaced, and unless I just didn't notice it, right after that my heater would only work on full-blast #4 setting. Once it gets warm I can turn the blower down and still get some residual heat, but it doesn't blow unless it's on #4 setting. I can hear a sound like a fan starting up when it hits 4, but no sound whatsoever on 1, 2 or 3. I've looked up everything from relay switch to motor blower resistor and can't determine which it is, if any of that. I also can't find a diagram to fix it. If it's an easy fix, I'd rather do it myself instead of paying another mechanic. I know the parts are somewhere behind the passenger side dash or glove compartment, but how do you get to it? Any help greatly appreciated.
just remove the glove box and its right behind it just take the white pug out and the two phillips screws to remove the resistor out, replace with the new one and cool off!!!! Hope this helps

Exhaust system needs a visual inspection to determine defective part.
Drain hose to evaporator is clogged.Put on eye and face protection, use a soft stick object to shake the debris from the evaporator hose free. Lots of cold water will fall on you if your not

You may have a faulty fan switch. Had mine replaced when only #1 and #4 were working and it fixed the problem. Unfortunately, there may be more issues, as a year later the switch is failing again. May be some kind of feedback that is causing it to fail.
