As I stated above. I knew what it needed, I know it would cost.. So how much would it cost to replace all the resistors with new ones ? Why just replace one when they all are all the same age and about the same use.$30.00-$50.00 each. A LOT !!! I put this up as a affordable option that works. As a matter of fact it works better than OEM as I have infinite control of the speed of the fan for any speed and it seems to go to a higher speed also.
