2001 xc70 blower motor vs resistor

bmhagthib · Post by **bmhagthib** » 06 Oct 2014, 15:37

I few months ago my fan would continue to blow after the car was off and come on at random times while the car was off. Well now nothing is happening on any setting. I'm not mechanically inclined by any means but did get the blower motor out (with the helpful instructions on this site). Only to find out that the resistor could be the problem. I'm trying to save money that I don't have so to speak so can anyone tell me how to figure out which piece is to blame or where I might be able to find both used and at a reasonable price. Any assistance would be greatly appreciated

Can you remove the resistor without removing the blades? I would say it's the resistor, the motor doesn't really fail, just try turning the blades see if they turn easily.

I did get the resistor out and the fan seems to turn without a problem. The resistor itself is very dirty and looks kind of like it's starting to corrode. I took a picture of it if that helps to determine if it's bad.

No reason to mull this over, just replace it, they go bad
