T3 Vanagon Cabin Air Control Kit

(2 customer reviews)




Fix what the factory forgot: Add a Fresh-or-Recirculate Cabin Air Control to any left hand drive Vanagon.


Complete kit adds a cable-controlled closure door to the cabin fresh air inlet scoop behind the front grille, and a passive one-way recirculating valve to the heater/vent box. Limit entry of cold air when heating and hot air when using air conditioning, making both systems more effective and easier to control, and the cabin quieter. When you close the fresh air inlet door, the passive recirculating valve automatically allows the fresh air fan to recirculate cabin air instead.


Can be installed in any year left-hand drive Vanagon or T3 pickup with any style upper grille in about two hours. Dashboard does not need to be removed. Pull-knob control cable mounts right below the rear heater fan control switch (see picture above). Requires drilling one 3/8″ hole in steel dashboard below existing ventilation control lever panel , or you can make your own under-dash bracket to mount cable.


NOTE: Due to the preferred material becoming unavailable, the kit will no longer include the steel mesh pest screens. These are not necessary for the primary function of the kit, but are nice to have so you don’t need to close the inlet door to keep rodents out. Templates can be downloaded on our Guides page so you can make your own screens with your own materials, if desired. The kit price has been reduced to reflect the omission.


Complete Kit Includes:

  • Steel inlet door with foam seals.
  • Stainless steel inlet door support structures.
  • Bellcrank rod assembly.
  • Recirculation flapper valve.
  • Pull-knob control cable and installation guide tube.
  • Every part and fastener required for installation.
  • Detailed, downloadable instructions.
  • Pest screen templates can be downloaded to make your own.

    Just wanted to take the time to review your air cabin kit .It is sooo nice to not have that hot air coming in on our feet anymore. Even with the heat turned off it was never truly off .Comfort level in Hot weather is so much better .
    The kit was well thought out and nicely made . Instructions were very good . Everything was well packaged . Probably took me 3 1/3 hrs to install as I had to remove a bit of the factory body puddy / caulk to get it to fit in place properly. Also took quite a bit of trial and error to get the door to open and close smoothly, I had to bend the arm where the wire connected to as it would just barely hit the door . Kind of reminded me of adjusting a problematic bicycle shifting mechanism.It was nothing to awfully hard . I am just very thankful that you took the time to make this thing . Impressed with overall quality. Think I will be giving your oil cooler kit a try as you have won my confidence
    Thanks Chris k.

    Very well thought out and executed design. I have a 1983.5 Westy which apparently has the diesel heater box which is just slightly different. The cable bracket placement on the passenger side prevented me from putting the air intake flapper valve on that side as designed, but it fits nicely on the driver’s side of the box. Just took a little imagineering to find just the right spot. Much easier with the heater box out and opened up. The front flap took a little adjusting as expected. Read through the directions carefully and you can’t go wrong. Great product!!!
