      Its about that time of year. The frost is soon on the pumpkin

      Are you hearing a whistling when your side vents are closed? Do your hands get that little bit of cold air blowing on them as they are on the steering wheel? Well I have the answer for you.

      Gently remove your side vents from the dash.
      For the center vent, I took a wire coat hanger and cut the bottom of it and divided that.
      I bent a hook at 45 degrees on one end and the other I made a finger pull.

      Insert that in the vent slots and hook the back of the vent on both sides and pull out.









      To remove the side vents.....
      Use a flat blade screw driver and pry it out at the top against the hard plastic shell (not the edge) and the dash



      I have had good luck in gluing the middle edges with thin coats of jb weld quick If there are holes then you can use a piece of tape on the front to keep it from coming through.

      Then carefully disconnect the movement cam link.

      Gently pry out the opposite pivot.

      Then twisting sideways you can remove the vent stop.

      Carefully remove the dead foam, you will need to make a template so you can tear it on one side only.

      Now using a piece of foam thin ( I use old mother board foam I have a ton of it )


      Place the dead foam on it and trace the outline be wide on the outside.

      Cut it outside of the lines a bit
      Now you have a new donut gasket.

      Work the foam around the Stop into the groove.

      Now trim it evenly around about ¼ of an inch

      Insert the stop with the cam side first, and be careful… then pop the other side in to place.

      Re-attach the cam arm…
      Now admire your finished work.

      Your side vents won’t whistle any more and the cold air will be totally cut off of your hands and won’t interfere with the side defrosters any more.
      PS. You can do the center vents the same way....

      Are your vents are so floppy they don't stay up...Do they need viagra?

      Carefully remove the vent from the dash.



      Pull the vent all the way pointing up.





      Using a small screw driver carefully pry the vent out of the
      assembly.





      Looking at your vent front back sideways.





      Take a piece of thin closed cell foam or self sticky smooth velcro cut some small strips.
      Stick a large piece to the side of the vent frame.





      Pry out the "top" vent bar.



      Attach small pieces of foam to the leading edge of the bar, and re-insert
      being sure that you get the foam under the fingers...





      Place back in to the assembly.

      Did this on my '86 and it works. Be very cautious in removing the vent housing... old plastic can be muy brittle. Couple add'l ideas: While you have the vent housing on the bench... clean it! I used some diluted Simple Green to rinse the small felt pads on each side of the louvered part. These pads are a friction drag and help the vent stay where you aim it. Mine were so dusty-dirty that they slipped around. Now clean, they stay where I aim 'em. Mother board foam? Us #2 pencil guys don't know and don't gots. I utilized scraps of a closed-cell foam usually sold as tool box drawer liner. Think Sears. Denser than the original VW foam, it resists wear better than the original open-cell materials. And btw, the foam donuts are actually oval in shape as is the plastic flapper valve. Trim your replacement material - both i.d. and o.d. - to match the oval shape, plus the overhanging bit, and they'll seal up super tight. Bye bye, whistling drafts. Good call, Briano [IMG]http://*****************.com/smile/emthup.gif[/IMG]

      Great writeup, I'm looking forward to doing my center vent, which is clearly closed and no longer attached to the machinery that makes it open. It never has. LOVE those coat hanger dealies!

      Well I figured that it was that time of the year again for Newbies to learn how to fix their vents....

      I didn't realize that this thread was originally started in 2007 or 8.....
      So heads up.
