[V8] Timed rear demister vs non-timed

[Steven B]

Looking at the schematic for the V8 the switch appears to contain all of the circuitry to create the timer.  There is no external module in a fuse box for this function.  
I would imagine the 1990 100 would be similar to it's V8Q sibling.  I'd say that the risk would be low that there would be a problem.  It should be pretty much plug and play.  The more I consider it the more it seems to me it has to be ... if the timer is internal there would be no need for any additional external connections.  
Good luck!
... and Merry Christmas to all the members of the V8Q list!  Or rather, should I say Frohe Weihnachten!

On the 1992 Audi V8 I owned a few years back the rear demister (heated rear
windscreen) was timed - it turned itself off after 10-15 minutes.

At the moment I own a 1990 Audi 100 TQ Sport Exklusiv, and that car doesn't
have this feature.

 

When I look in ETKA, I see that there are several different switches for the
rear demister.

 

Can I just replace my non-timed demister switch for a timed one, or will
something fry? :p
