So in the process of replacing my heater core, I came across a little plastic tab connected to one of the vaccum actuators that attaches to the door that controls weather the air goes to the dash vents or the floor vents.

Well, that little plastic tab was broken so the door was halfway between and I was getting air in both places. Unfortunatly I couldn't find a replacement so I took to making one of my own.

Attached is a pic of the old tab (broken) and the two new tabs that I printed out on the rapid prototyping machine we have at work. I work for a SolidWorks reseller so I whipped the model up in SolidWorks this morning.

I am gonna try this out when I get home and if it fits I will post the .STL file so that if anyone every needs one in the future, they can have it done at their local rapid prototyping shop.

UPDATE: Well, this thing fit perfectly so I have attached the source STL file in post #3. My prototyper uses pretty flimsy material so I don't think it will hold up very long, I would suggest if you have one made, get it done in some nice ABS or even aluminum for longevity.

GOOD WORK. Mine used to be broken, and i think its broken again.

Want to whip me one up while you are at it?

I'll cover your time/shipping etc....
 
STL File

I'll do you one better. It fit good so here is the STL file. If you take this to any local rapid prototyper they should be able to whip one up pretty fast. I know there are tons of those places in the Bay Area. Our machine uses some pretty flimsy stuff that I don't think will hold up very long but it good for checking fit. I suggest having it done in a nice ABS or even Aluminum.

Aluminum would be best... if you could make it.

You can buy a bag of 5 of them like I did... think it was around 10-15 bucks. search under the part number in my post.

Plastic tab

Did you say that you had the plans to build this somewhere.I was in the middle of replacing mine today and came across the same thing. I am new to this site and it has a lot of great information on it.

I look forward to any information you have.
Thank you,
JJ

I don't have any plans to produce them but post 8 has a link to replacements and post 4 has a link cad file attached that you could take to a local rapid prototyper and have made.
 
I just got done replacing the heater core with the new clip. But, now my heater or A/C does not work. Any ideas???

Thank you,
JJ

The file is just a Trust file. Can you email it to me as a DXF profile shot? I have access to water jet.
 
I dont have a dxf of it unfortunately but i am not sure water jet would work anyway because there is a pocket in the part. If you download a program called eDrawings you can view the file and see what i mean.

Did your STL parts fit just fine? any filing or anything?
 
Nope, they fit great. I did a couple samples till i got the fit perfect so the final model should be good.
 
I'm thinking this is my problem... Heat works great but I cant change where the heat comes from. it just comes out of EVERY place a little bit. I cant find any broken tabs or ones that look like the one in the OP. where should I be looking and how much dash has to come apart to get to it? I really have to get this done cause not being able to defrost or even defog the windshield kinda blows:doah:
