Last month my blower would not turn off. I replaced the Final Stage Resistor and it fixed the problem. Now my fan is stuck on again.....any Ideas? Is it possible that the Final Stage Resistor went bad again?

FYI, its a 2001 X5. The fan speed is constant and does not change regardless of how I set it. The only way I can get the fan to shut off is by removing the final stage resistor. As soon as I re-connect it, the fan comes back on.

Thanks in advance.
