Hvac blower fan failed after two years of ownership. Unfortunately vehicle mileage exceeds warranty period. Dealer said that failure was due to not clearing snow from hood, thereby blocking air to fan. However, vehicle is garaged and not subject to elements. Mechanic indicated that he had seen other similar failures and that they were due to seepage of water into blower housing and subsequent freezing.
No heat. 4-runner was brought into dealer for service 3 times because blower not working, and dealer is now saying they are not sure how to fix. They are waiting to hear from corporate office on how to repair. We are told this is not an isolated problem and they are getting more of this in other 4-runners. They say moisture is getting into blower and in cold weather it freezes causing it not to work. So we are still waiting to see how they will fix this problem.
