02/CRV, no heater fan = bad resistor(?)
 

All of a sudden our CRV's heater fan quits, but heat still finds its
way to the vents. Windows eventually defrost, but this will be a big
problem in Newfoundland later this winter. The local Honda dealer
diagnosed the problem as a "resistor" needing to be replaced. The
part is on order, but it'll cost me $200+install!!

My question is what kind of resistor plays a part in the fan failure,
let alone a $200 resistor? What options do I have?

TIA & cheerios from the Avalon Peninsula :o)
