Too much cold air

[Thomas591]

While I was driving my 411 S5 today -outside temperature -4C i encountered the problem that my right hand became very cold because the adjustable nozzle on the right side of the facia could not be closed completely. Also visually the flaps inside the little ball very seemed to be close, way too much cold outside air passed through it. Any Idea how to overcome this problem? Are there any gaskets inside the ball that needs to be replaced?

Have you tried spraying with WD40 to see if it frees up the parts? It seems to work well on plastics.

Morning, it's not as cold as that where I am, but have had minus one and 410 seems to love it once you've got some warmth in the engine and gearbox oil.
I don't know if it's the same but in Austin's and similar that I've owned with eyeball vents the sealing inside the vent was accomplished by bits of felt that over the years became loose/moved slightly and prevented it closing/sealing properly.
The Jensen fellows have a solution which may help https://www.martinrobey.com/jensen/i...on-cover/15104
I've managed to get them working in most cases (as suggested below) with judicious use silicone spray to get the parts moving smoothly so they could force their way closed.
Other solutions have included wearing a single glove and blanking the vent off until weather warms up. I appreciate that these solutions may be acceptable in an Austin 1800 rally car and less so in a Bristol!
