My car has never had a hose behind the dash side vents, only the side vents. I saw on the GT forum that the dash side vents go directly to a hole in the firewall next to the wiper assembly. Is that where they go on the spider as well?

Anybody have an answer to this? Red Racer maybe?

Thank you

Yes. There should be a hose running the the cowl for fresh air.

But there are exceptions. What year is your car?

See if I can help you.

Randy,
I'll try to get a picture tomorrow to better explain the ducting.

Then it should have the holes.

Spiders with factory A/C did not have the hole cut out in the cowl. Usually 1982 and later.

Pictures that may help. This is of the cowl hole with & w/out vent hose attached. Scuttle drain hose is also in pic

Those pictures are great!! I will be under the dash tonight looking for mine. I also like the way you did the drain. Looks like vacum cleaner hose is that what it is?

That drain hose is an OEM from Classic Alfa UK. They are a pain in the neck to install through the rubber grommet while keeping rubber in the mounting hole.
One more thing to mention, there is a clip to be installed after vent tube is in place. unfortunately, clips on mine are AWOL. if I had one (which I'm looking for) to picture, I'd post.
