I have had my 04 4Runner for a few months now and I have noticed the defroster doesn't work as good as the defroster I have had in other vehicles. If I put it one setting below max fan it hardly works (blows fine but won't clear the window) or if I have it on max split between the floor and defrost vents it doesn’t work that well either. If I put it on max fan and defrost only vent it clears the window almost instantly. Is this normal?
