I had noticed more wind noise from the rear when driving on the highway. So I pulled the rear C pillar vent grills and ducts out for a look.

What I found was the 26 year old rubber flaps had dried out and curled so they could not seal the openings.

I went down to a local aerospace supply business and bought a roll of silicone rubber sheet and cut out replacements using the old flaps as templates.

The original flaps are stapled to the duct, so I removed the old staples with a screw driver and pliers quite easily. I got to thinking that Mr. Toyoda (family spelling) thought staples were OK, so I used my Arrow t-50 stapler with Monel 1/4" staples to attach the new flaps.

I placed the ducts with new flaps on a block of wood and stapled right into the block. Afterwards I took pliers and bent the staple tips over for extra security. Easy!

Cleaned everything up and put them back in place. The whole operation took about 15 minutes to do both sides.

Below are some pictures.

The road test confirmed the noise was gone, and since it was hot I had the AC on. I think the ac works better also?

No matter what, it was a quick and easy repair with a product that will outlast the original parts by a long ways. If anybody wants silicone flaps I have enough material for more sets, check the "for Sale" section later today. I want to cover costs of the $$ilicone sheet.

Cool replacement job there.

I had taken mine apart, they were unstapled. I cleaned them up and used my rivet gun to put some rivets in the plastic duct.

Kind of a cool little vent. I think it helps pull air out of the cabin to allow the air conditioner to cool further back in the cab faster.
 
Nice simple fix, Doug ... I've got to do that to mine, also -- Have the same noise. Save a pair for me :D

I believe that vent also helps ventilate the roof space...
 
local areospace supply business? Nasa Depot?
 
I love it! I just did mine too. I did not use NASA Depot I used Home Depot. I had some shower pan liner left over from my inner fender skirt project. I took out what was left of the old ones made a template and cut some out. I also used 1/4" arrow staples to secure them. [STRIKE]I have a bunch of liner left over if you want a pair I will mail them out to you for $1.00 per set (postage included). Just PM me your address. I don't have unlimited material so this offer is as supplies last only! Local pick up is free. [/STRIKE]


Doug720 used a much higher quality material than I did please see below



EDIT: Sorry Doug720 don't want to step on your toes. I wont accept any order until you are sold out. Please go to to Doug 720's link to purchase C-Pillar vent flaps

I saw this old post and wanted to revive it!... I opened my vents and the rubber seals are dust, so I don't have a template or any thing to go off of. Any chance there is somebody who still has a template or material?? Let me know, if not, I'll try to make a template.. thanks!

I'm in the same boat, my are non existent, but I wanted to get them redone before I drop a few hundred bucks on redoing my AC system in this Nor Cal heat
 
Just did this while grilling dinner! My "flaps" were gone. Had some stuff laying around that I thought would work. Great post! Thank you!
(I'll let you know if it cuts down on the road noise from the drivers side that always make me look back to see if the door is latched)

Did you just guesstimate on sizes?? Mine were dust... so I was hoping for a template or dimensions... any thoughts? Or is it just a figure it out once you are in there kinda deal??
 
I just cut the stuff a bit smaller than tight, so it could move with the change in airflow. It was easy to figure out once I got in there. I did make one that was a scoatch to small at first. Very easy to change if needed. Just be gentle with the gaskets on the vent if you still have them. HTH.
 
You could probably try cutting up an empty coolant jug for material...if there is no other material around, if you can live with the color of the jug!
 
Thanks for this thread. Pulled my covers and my flaps are toast too.

Question for those who did this: Are the vent ducts pulled out from the outside?

Thanks
 
Dimensions are roughly 4 5/8"(length) x 2 7/8"(width). There's roughly a 10 degree angle on the bottom. I have mine out and can take pictures of the flap if that helps. I was washing the vent and the rubber by the staples ripped like TP.
 
Yes please post a pic or two! Thanks!
 
Always.....something! Another thing to check especially after paying lots of $$$ to re-animate the A/C system!:cautious:
 
Which way is air supposed to flow at those vents? I've assumed they were exhaust vents but the flap pictures look like they are intakes...
