Center Vent Not Holding Position

It's called goop in a tube strategically placed a few dots will hold vent wer you aim and put dots of the stuff not heavy you shouldn't see it wen done . Get it right once it stuck you have to break seal and roll up to get it to glop around again . Or junkyard .

 

When my gen 1 was doing that I waited till I had the center dash out for another reason, and I cut a couple slivers off a thin rubber sheet and stuck them in the grooves where the vanes pivoted. It worked nicely.

 

A change over the years in the coefficient of friction between the moving part(s) and the nonmoving one(s).

I found that just adding a couple strips of thin rubber behind a vane's pivot points made it nice and secure again—easy to move on purpose, and not moving by itself.

I'm not sure what kind of goop in a tube Tom used. There are lots of kinds of goop. I assume it wasn't the hand cleaner that's actually called GOOP. I wouldn't really think of hand cleaner for that.

 

I have a big sheet of, like, 1/16" thick rubber, maybe EPDM, that I bought somewhere years ago, so I cut a couple slivers out of that.

You've got a different car with different vents than my old gen 1, so I probably can't help much with where specifically to install. Once you have the vent assembly out and you're looking at it, you should see where the piece you'd like to hold position better has pegs where it pivots in something, and that's what you'd like to make just a bit tighter.

 

You could try a bicycle tube, from a thin tire. Or perhaps a rubber glove?
Pull the vent out, put a small piece of the glove over the hole and put the vent in.
The little tab will be tight.

 

Goop it's made for plumbing and shoes used to be called shoe goop grey tube red letters and spelling above repairs many things excess can roll up and not be seen . My Gen 3 couldn't make it long enuff for vents to fail unfortunately 2 or em . Amazing Goop States on label very popular stuff many years
