Default Did I break the comb filter pivot?

Twisted it to get it off, replaced the bladder, now I can't seem to push on with a screwdriver.



Ye olde flap arm, buried in the car



So: Did I break off the mounting ears/whatevers? And if so what are the options on fixing it and just how much do I really care about this? :-) Wondering if it's possible to get a screw on a very long phillips screwdriver and put a screw in the plastic. Or would I need to first use a very very long drill to drill a tap hole (ie: Might I break this off the flap as discussed in (https://rennlist.com/forums/928-foru...tor-arm-2.html)

I hate 30 year old plastic....

Thats a great picture, how did you get this?

That pivot point does look to be damaged.
I dont know of a solution either.

This is the attachment point for the vaccum actuator arm for the comb flap right? Where you have to get to it from the side after removing the glove box?

yes it looks like the view is through the small hole in the glove box surround.

Yep. That is a $15 endoscope type camera mounted to the blower vent with jeweler's green tacky crap. Stuff is amazing, keeps small things put which is nice. I also have a flexible LED light shining in there to augment the main light. It's probably *the* most useful $15 bucks I ever spent on Ebay, that thing has a million uses once you have it.

But yes, it's broken. And it is exceptionally hard plastic, so I can't thread a screw into it from the outside. In addition I noticed that the comb flap was shoved *in* and thus was stuck and couldn't move. Not sure if I broke it or it already had sheared, but either way it's toast.

I thought about taking the entire dash out so I could remove the front of the AC system and basically rebuild everything from the ground up. Then I realized I would need to pull the dash and I might as well get the reflectors so the dash lights look better. Then I realized I would need a third bladder (the larger one) to do the defroster flap which is also shot. Then I realized I could pull that plastic cover thing on the dash and send the whole thing to be factory rebuilt. And I could then put in a proper steel stud for the flap arm so I wouldn't ever hae this problem again.

Then the outside temp hit 80 degrees and I thought "Well, sod that". So I started putting the center console back in.

Halfway in I realized I had forgotten to put the spring in the comb filter servo, then just quietly got up and closed up the car. I'll try again next weekend if the temp is below 70. But I think what I will do is put the spring in the servo so I don't lose it, then close everything up, and forget about the whole comb flap. I'll use the tacky to hold it open in the summer, and same to hold it closed in the winter.

Based upon what you wrote, a heater box R&R is in your future at some point. There's no good way to fix that bit of old plastic if it's truly screwed-up when trying to work with the heater box installed.

Sucks.
