Thanks so much for doing that dave - sincerely -
Mine looks just like your pictures. No pushrod attached to anything. So does the pushrod attach to where my arrow is pointing? Does the pushrod have a bend in it that goes into that green looking compression fitting? Correct me if I am wrong, but your flaps, if installed in a car, would not work either as the pushrod is not connected to the flap, right?

There's actually two flaps there. I'll see if I can get a better picture. The pushrod goes from the actuator to a flap that's connected to the flap you see with that white plastic pushrod. Looks like a biplane wing, almost.

The actuator opens the lower flap, the white linkage closes the upper flap at the same time.

This is the end of the linkage on the lower flap. The black plastic on the left is the underside of the mounting flange. You can also see the left foam gasket to the upper right. Installed in the car this would be right at the firewall, just inside the cabin, well inside the dash.

Thanks Dave! I was just logging on here to post what I found out. I ended up just pulling the whole freakin thing out. Had to pull the blower motor to get the upper housings out as it spans across behind the motor. Those holes I thought were for the actuator rod were actually holes created when the bottom flap you are talking about were broken.....on both sides.

On the driver side, the broken ball joint thing is still attached to the rod:

But on the passenger side, it is missing:

sort of related, you can also see how the lower housing is all mangled. I guess the original motor disentegrated or something as the current motor has yellow paint pen on it...but there was no rubbing or noise so I'm not going to worry about that part.

So this leads to numerous questions.

1. Well not really a question, but...I'm going to pick up one of those flexible springy grabber things with the three little prongs that come out and see if I can't fish around within the housing and find the broken piece to the passenger side. That would be the easiest and cheapest for me.

2. What sort of plastic is this and what sort of epoxy or adhesive or glue or whatever can I use to reliably and permanently glue to broken part back on? What solven to use to prep the plastic beforehand? I'm probably going to take it by a fastenal store to see if they can assist with that.

3. Lets say I CANNOT find that missing ball joint piece. Would it be feasible to permanently close off the passenger side with silicone or adhesive (lock the flaps closed) and only utilize the driver side for fresh air? Honestly, all I want fresh air for is for defrosting purposes on humid days or in the winter. Would one flap give enough you think for that?

3.1 - The driver side motor for the flaps is kaput. Will the passenger side motor work on the driver side if I close off one side?

3.2 - If motors aren't interchangeable, where do I find that part?!

4. What can I use to restore the corroded foam on these? Would have to be some thin stuff. Or should I even bother?

5. OK, lets say I can't find the missing piece, permanently closing one isn't a good idea, so I need at least a passenger side upper housing. Where the heck do I find that thing?! I find nothing on Google.

6. Dave, would you willing to part with any of that magnificent example of blower housing goodness you have there? I bet you are keeping it for a spare

I thought I had other questions, but I guess that is plenty, huh! I'll say this, hopefully some other poor schmuck on the interwebs will be able to find this thread when he gets to looking at the same issue later. I guess that is kinda the whole point of forums, huh?

Dave - thanks so much for taking those pictures for me. What is your favorite place to eat. I need to get you a gift card or something man.

I remembered my other questions:

7. That wire harness going above the passenger side pushrod. That seems like it would eventually rub a hole and short out. Dave, does your have a wire running through there like that? All I can think to do is armor it with duck tape and zip ties or something.

8. Any suggestions for cleaning the heater core out down there? it was pretty gunky and i brushed/vacuumed out what I could when i changed the resistor. Isn't there some sort of spray or something to eat all that sticky dusty gunky crap like you use on an a-coil in a house HVAC? Or is that a bad idea in here?

9. What else should I do while in here? I read something about the elephant trunk or elephant hose or something? I don't have any leaks into the cabin that I can speak of or know about. It has only been in the rain like 3 times. I know the trunk has a leak somewhere around the tail lights but that is it. Anything else I need to address while it is all opened up?

argggggg! The part number should be here!!

looks like parts 04 and 05 are the actuator and connecting rods and they are universal. But there is STILL no number for the bypass flaps - part 08 is the stupid plastic connector thing between the two flaps, but no flaps?!?

I wasn't keeping it as a spare. Not that I'm saying "eat your heart out" but I have two...I suffer from this version of hoarding that makes me keep everything e30 that nobody else wants...I'd send the whole deal your way for like $25, but it's a mess. Heater core is dead, as is the condensor. Case is likely the only good part and it's covered with mildew. Shipping would likely be expensive...where do you live? Maybe we can work something out.

No problem with taking the pics (I re-organized my stuff so it was all good)...but I like sushi...and beer...LOL!

my zip is 38632. Would you be willing to take parts off or do you only want to move the whole thing?

DesktopDave · « **Reply #24 on:** March 22, 2012, 03:59:41 PM »

Small parts would be a lot cheaper to ship...lemme know what you want.

I still want to put 12v to my motor to make sure that isn't a wiring issue, BUT:

At least:
1. Both flappy/bypass/recirculation doors (I guess four flappy doors really as they are connected)
2. One of the actuator motors - if you think it works
3. One of the little tie rod end/ball socket things off the actuator rod

If easier for you to just pull it all off and send it:
1. Both the driver and passenger side upper housings with the flappy doors attached
2. Both actuator pushrods with the little tierod end thing attached
3. One of the actuatator motors - if you think it works

My driver side housing that holds the drivers side flaps is a little chewed up from where the fan must have disentegrated previously, but it still works ok. I don't really have to have the whole thing, and I'm not sure if you wanna retain what parts I don't absolutely need for yourself or someone else or not. Physically, probably easier for you just to pop the retaining tabs, pull off the whole housing, pull out the rods, and chunk it in a box. It is up to you. Whatever is easier for you. I really appreciate it! Let me know how much I owe you, and make sure you include some cushion for your time!

PS - I'll get 12V to that motor tonight so can let you know for sure tomorrow that I need a motor......

tfrain · « **Reply #27 on:** March 23, 2012, 08:35:10 AM »

I need the motor. Let me know when you can get the stuff sent and how much I owed you. I sincerely cannot tell you how much I appreciate it!

Gah...you're cutting into my quality e24 time!

Just kidding...I'll let you know what I can fit in a box & PM you my PayPal info.

You know, everything for a 6-series costs like 3x as much, right? Looking at it that way, you're actually saving me money. I should be paying you!

tfrain · « **Reply #29 on:** March 26, 2012, 09:37:55 AM »

Ha ha - thx Dave! Did you know that Bob Lutz had some influence on the E24? I did not know that, but wikipedia did? I bet stuff is mucho expensive for your 6-series. Lemme know how much you need for the parts. I'm ready to get my car back together. The civic just isn't the same! I ordered a new radio and speakers for the back deck that I'm going to do while I have the dash apart.
