I'll sell you a working used unit for $100, but before you buy it, or run out and have yours rebuilt, why not find and fix the actual problem first ?

Have you checked power and ground at the motor ? You have an open resistor. Replace the resistor and the fan will work. How do I know this ? Because they often go bad, and if you knew to check it, you would have mentioned it above. So, you haven't checked it, and are about to replace a very expensive component because you _think_ it is the problem.

While you may not necessarily fit into this category, I wonder if perhaps you are the type of person who screams about the ludicrous hourly rates at shops, even though, in this case, an hour, at $85 per, would save you hundreds of dollars !

This is not meant as a flame, take it anyway you care to..........
