above heater controls center of dash
It is at the dash board bottom just at the middle. You can see a plastic rectangle were the heater core is and at the right side are the pipes that goes to the coolant valve at the engine
look in how to bleed air off cooling system
you will need a new thermostat to cure this problem. ian
Sounds like "heater core" is shot-any coolant leaks inside the car coming from under the dash?, Have check, replaced. Or could just be an air lock in coolant system, which is better easy fix.
I have a '92 Previa. The fuses are located under the dash board above the heater controls. There is a small latch above the "AC" button. Probably more fuses hidden elsewhere, who knows? Hope this helps.
if it is the same year as mine 92 it is right in the cent over radio and heater switches just lift up and you will see them and also arer the breakers
