While driving my 2001 Toyota rav 4 ( 31000 total mileage ), with the heater motor on high, I heard aloud whirling noise. After a short time ( 5 or 10 minutes ) the heater fan stopped working and the smell of burning wiring filled the vehicle. I immediately shut the fan switch off. A wisp of smoke came out of the dash vent. Examination of the fuse box showed that the fuse for the fan had not blown. I believe that if I had not turned the fan off there would have been a vehicle fire. After further inspection I discovered the dashboard was covered with fine particles of an undetermined origin which I assumed came out of the windshield defroster vent. Repairs have not been made.
