If someone out there has had this happen or knows how to replace, PLEASE help me. I have a 2002 Sentra SE-R. From research I did, I found out that my problem should be the resistor block as only my high speed of my fan works. Can someone tell me where it is? and How to change it?

Thanks a bunch
Ryan

 

It's basically just a circuit board that you disconnect and reconnect the new one ..... if you look at the heater box behind the glove box you should see it.Pm meif you are interested in purchasing the part.
