1991 Mazda 626 heater blower not workking

Here's the situation.



I have a 1991 Mazda 626, for the longest time the blower was only working on speed 3 & 4, finaly that gave way and the blower does not work at all. I temporarily jumped the blower motor via the cigarette lighter with an old power cord designed to use the lighter as a power source (this worked for a few days but now my lighter does not work and no fuses are blown). Of course It was unpluged from the lighter when the vehicule was not in use. I have since purchased a new resitor pack from the dealership and pluged it up as it was originaly, the blower does not work. When I engage the fan switch to positions 3 & 4 the engine revs high and low for a second but the blower is inoperative. All fuses are good, first of all, what elese could be the problem and second, how do I troubleshoot my new lighter problem.



Any help would be appreciated.


Thanks in advance

Your blower motor is bad. It is pulling too much current, because it has a shorted turn in the winding, or bearings that are gummed up, or both.

This is what has damaged the resistor pack, and has since damaged the lighter wiring.

Thanks Scott,

Would you recommend a blower from a scrap yard or a new one?

Depends. If you get one from a scrap yard, you're probably going to want to clean and lube it before installing it anyway.

For a lot of these parts, a new one is almost as cheap as a junkyard one, since they are such a pain to pull. For others they aren't.

With all junkyard parts, you pays your money and you takes your chance.
