View Full Version : Duct Debacle

06-15-2011, 01:13 PM
OK, as I was investigating my leaky heater core issue, I found that none of the ducts under the bow of my (new to me) 1999 Prostar are hooked up. I think they have just fallen off the inlet openings over time. I see there are two hoses per air inlet Looks like one from each goes to the dash defog and the other to the engine compartment? Also, does it matter which hose goes where? Help!

Don't think those ducts are for your heater.

I have a fresh air intake that comes from the deck, and provides fresh air to the engine compartment. Then there is another duct, that goes from the engine compartment to the rear vent.

These are seperate from the hot tubes ducting...sounds like they may be missing.

Need pictures!

sounds like the fresh air inlet for the engine

There is no defrost that I've aware of. Those are for the fresh air. I have the same for my X2 and the just hang down to advance air flow.
