Astro Vent 70 Vert
I recently discovered the rear deck vents are operated by vaccum. Can someone tell me where the vaccum line connects to in the front. What is the forward control that operates these vents?

The rear Astro Vent door operates from a vacuum source off of the HVAC control wheel. When the heat control is turned to hot, the rear door closes; when the control is on cold, the door opens. At least this is how it operates in a coupe, I am guessing a vert is the same.

Only closes when the heat control is set to hot.

On factory A/C equipped cars the Astro Vent system is non-functional and the vents to the inside of the car were blocked off with plates. I guess it has someting to do with the A/C fan always running on a low setting to circulate air through the cabin.

I now have my 1st factory NO AC car. I was amazed to find the vent door (vacuum operated) under the rear deck. My other c3s were (are) factory AC cars and I don't recall ever seeing the vent door at the back of the rear storage area. I will check tomorrow to see if it actually CLOSES when I select the temp to "hot". I have never seen it close....but I don't think I have ever LOOKED when the temp controller was moved to "hot".
That's what I like about this forum...I always learn something new.

quick question about the rear vents. when the car is turned off, what position are those vents supposed to default to?
i guess more importantly, is there any way to lock them into the closed position, with out glueing them shut?
im getting really sick of not being able to keep anything in that rear storage area because it all gets soaked when it rains.

Look underneath where the vents are for rubber tubes and make sure theyre clear
Mine are wide open and I get NO water in the back

Im sure there are seals/gaskets avail for these vents.
If you drive in the rain and you get water it could be coming from below.... holes or cracks in the pans
*EDIT* center row very bottom.

i think ill probably pick up that rebuild kit. the seals are atleast 20 years old on it right now.
i would drive it in the rain, but there are other problems associated with that. for instance, a dead wiper motor that i havnt gotten around to swaping out yet.

Doc Rebuild has been very good to me
Of course I only live 20 miles from their warehouse so I just call them, they pull the parts and I go and pick them up

On my vert the rear vents are open as long as the control is on full cold. Turn the dial in the hot direction any and the doors go closed.

AMAZING....I just tried it....the damn door closed when the temp is selected to "hot".
