While disassembling my heater box to replace the core and motor, I found that part of the plastic has broken off (big gaping hole), and I'm also missing the shaft retainer on that side.

I've had the van since 2001, and I'm pretty sure it's been like this since then (17 years!).

Looking for opinions on whether I need to replace this part or not, if it's even available.

Thanks, Leo

Unless this part is readily available, and at a good price, I'd start thinking about just repairing it. Glue, rivets, aluminum sheetmetal, etc.

Agree. I'd just use that quality metal tape for ducts to seal the hole, or another strategy with sheetmetal and epoxy, etc. No biggie. As for the shaft retainer, one of mine was broken and I just set it in place with some RTV. When I saw yours, I thought "Heck, I'd just trim a piece of plastic with a rounded notch for the shaft to pivot in and RTV it in place. It doesn't take much force - the shaft just rotates in it. A spot of grease before you put it back in the dash and you're good to go another 20 years.

all you need to do is retain the shaft in place so that it can rotate and not drop down via some plastic + screws, etc. the opening itself doesn't matter as that is the floor outlet post damper plate so there's no place to 'leak' air other than where it was going to go anyway.

JB plastic weld is the route I would use with some Popsicle sticks etc.

Think MacGyver and yes for metal duct tape.

I would rather find a good used unit. Since you have an '84, why not find a later model unit that has the better style fresh air duct routing. While you're at it, think about the Vanistan fresh air/cabin air recirculation kit.

That's a great idea, Hans. Unfortunately there seems to be none of these for sale anywhere. I'll keep looking.

Try VWcultmember in the classified section. He seems to be parting out vans.

I have a heater box complete from a '91. I had it in the classifieds for a while but the ad expired. If you want it we can work something out....

I think Sleepyjoe is on your coast, contact him. Shipping from the right coast may be $$$.

I took Hans' advice and procured a later style heater box. It does have two additional ports compared to the original (I think) that came out of the van.

What I don't understand is that these two ports are blocked off and won't do anything if I hook them up.

What am I missing here?

Also I included two pictures of the p/n's molded into the box. Same part number for both except the older one has a suffix B and the newer one has a suffix of C.

Bump. Can anyone give me the skinny on these two blocked off oval ports?

On the later style heater boxes, those oval ports were opened up. Those are the feed ports to the outer most dash vents. On the later model vans, the ovals are opened up and the large circle ports are closed. On earlier vans, the oval ports are blocked and the round ones are opened up.

The main difference being where the air is drawn from in the heater box. On the later style vans, the air is drawn from the oval ports which is after the heater core, so you could have heated air coming from the dash vent. The early vans drew the air from before the heater core, so you could only have ambient air coming out of the dash vents.

See this thread for more discussion.

So it's an either/or situation. You're either using the circular ports or the oval ports, not both at the same time?

If I decide to use to the oval ports, do I need to get matching oval shape tubes?

Yes, it is an either/or situation, you can't connect them both to the dash vents (without some custom work, anyway)

If you used the oval ports, ideally you would also need to use to matching oval hoses. I've seen them for sale in the classifieds in the past, so it may not be too hard to find them. Of course you don't have to use the oval hoses, that is just what would be the easiest. You could certainly try to modify your current round hoses or use some sort of adapter to connect the round hose to the oval port.

One last question, rev. I'll need to open up the blocked oval ports somehow, say drill some through holes and then dremel out the rest, correct?

And then block the round ones also.

Correct. If you plan on using the oval ports, you will need to open them up. A dremel tool or similar should suffice.

And yes, you will then need to block off the larger round openings. That would be pretty easy to do. Just find some sort of cap that can be adhered to the opening, or make a simple block off plate from plastic or sheet aluminum.
