How to fix "Vent stuck on Defrost" Minnie Winnie. Video

Hi Guys. So, the vent control on my Minnie Winnie was stuck on defrost. It took me a while to find the problem because the issue was in an inaccessible area sandwiched between the firewall and the fender well. After discovering that it was cost over a $1000 dollars to have this problem fixed by a mechanic, I did a lot of research and I figured out how to fix this problem in less than 30 minutes for about 25 cents worth of tape. I made a video of this drop-dead simple process so that other people can save themselves a lot of time and money. Here is a link to the video.

    True, but it works most of the time with no problems and the low vacuum goes away fast. Plus, as I said in the video, you can add the vacuum pot under the dash very simply now that the T-Valve is located in an easy to get to location under the dash. I have one on order and will add it when it arrives. But the fact is, it is not necessary for the system to work.
