Steam From Defroster??????

pdremer · 12-13-2003, 01:43 PM

Drove the car to diy car wash to clean underside of engine and trans. Sprayed all around underneath.

On the drive home, whenever I made a turn, steam would come out ot the defroster vents.

Does this mean something? I'm afraid some part of the heater duct work has rusted thru. I know there are about 3 quarter sized wholes on the outer rocker but these shouldnt allow water into heating ducts.......right?

Thanks

more likely a seam in your heat exchangers.

maybe the fresh air vent drain is clogged

Heater exchangers are SSI. Tho very good quality, I'm sure there is a way water under high pressure can be forced into them. Hope thats whats causing the steam. If so, NO FIX required.

Cas is a 72 911.

Where is the fresh air vent drain?

Thanks

the fresh air manifold encloses the mesh outside vent. at the bottom of the manifold on my car is a plastic flex accordion type hose that extends under the car.. mine sticks out about 1/2 inch down under.. perhaps an eyeball from down under
