With regards the caller who was drying her cloths with the defroster and lost the fan. I had the same issue (not drying cloths), but the fan stopped. What makes this hard to diagnose is the fan has the 12v + source and the switch is the ground so diagnostics can be deceiving. In my case, it turns out the connector under the dash C206 is a bit undersized and after pealing away the foam, I found was the terminal was burnt. Has 14g DG on one end and 12g BK on the other side (Pin J). Had to do a bypass and the fan is a happy camper again. So don’t be too quick to swap fans on this one.
