this was very helpful to me and the guy who posts the videos has his own website which if you email him any questions, he will respond. Whether the blower motor works on certain speeds or doesnt work at it, this will cover it.
Hope this helps

I cant see the youtube video at work so I don't know what it is, but the blower motor resistor will fix the problem. Mine only worked on 5. I replaced the resister and it is working fine now. Its below the glove box on the bottom of the blower motor. Took me about 20 minutes to change. It was clearly burnt up. Cost me about 25 bucks i think.

mine only worked on 5 also. i swapped out the resistor and it works fine now. make sure to replace your cabin air filters too, for 2 reasons.

1-probly the reason why your resistor fried up is because if your filters are dirty/clogged the resistors overheat because theres no or not enough airflow over them to cool them.

2- they are right there in the same spot as the resistor so ya might as well.


i had about 8yrs and 160,000 miles worth of "stuff" in my cabin airfilters before i realized my hoe even had cabin airfilters. the filters were BLACK with tons of junk like those propeller tree seeds, pollen and other gunk that came pouring out when i removed the filters.
