Why is the fan on in my Toyota Avalon not working?
If your Avalon uses an electric fan to move air through the A/C condensor/radiator assembly then the fan motor itself might be suspect or even the thermostatic switch that turns the fan on as the coolant temperature level begins to rise. You can also reduce the heat load on the radiator by running the A/C in the most, more efficient mode.
