Greg,
This is common on many cars, not just Spits. While it could be caused
by a leaky core, it most likely is simply due to condensation inside the
heater box itself. When the fan is turned on, the moisture is expelled
onto the windshield and after a while, only dry air comes out which
dries it up. I'd say, your best solution is to warm the car up for a
while before taking off and make sure the defroster is ON so that when
you are ready to go, all is right with the world!
Cheers,
Joe
