Title: Finished my first DIY problem/solution on the 1992 S4
Post by: 92UrS4 on June 10, 2007, 07:30:53 PM
It feels good to be getting back to the things I enjoy doing. So a few weeks ago while wanting some AC I thought it was strange that nothing was coming out of my center vents. As I learned the flap valve things have a tendency to go out and I figured that's what the issue was. Last week I printed out the commands and listing for problem codes that can be accessed through the climate control system. Surprisingly, no faults anywhere!

On our way back from Wyoming today I was roasting in the car and the SC just wasn't cutting it only coming out of the top (def) and footwell vents. I mean my feet were cool and so was the windshield, but I wasn't. We are heading to Vegas in a few weeks with friends and this just was not acceptable. After washing the car thoroughly of all the bigs and roadkill debris that was on my beloved S I decided it was time to tackle this problem.

I hoped on AW and did some more searching and found a guy with a similar issue. His problem was the opposite, center vents worked, and so did the footwell but no defrost. It turns out this little bugger servo control thing popped off. So the system couldn't close off his center vents.

After dismantling the glove box I could clearly see the problem:

Now the trick was,  how to get it back on. The servo controller on the inside of the blue piece has one side that's flat and the rest is grooved. The white post above is the same way. I got a bit frustrated and then I was like, doy, turn the car on and play with the controls until it lines up. Voila! On it went.

Of course I have no idea how it worked itself off or how long I have until this happens again. At least I know how to fix it. It nice to have AC coming out of the center vents.

Oh and for what it's worth, in the winter I am always used to having my heat come out the defrost and footwell vents. I just prefer that, keeps the windshield clear and heat rises. So I never really noticed the problem until it got warm.

There ya have it, now it's time for a Coors.

nice, I would imagine that without those pieces lined up, one could be futzing with it forever.

Glad you got you some chillin vents now :)

Well if it breaks again at least you have the luxury of driving up a few thousand feet and cooling off,  I have to run my AC 80% of the time down here.
