REAR DEMISTER QUESTION...???
 

Does the rear demister on a Classic - specifically on my STi 5 - automatically turn off after it's demisted the rear screen, via a sensor or something? Or does it just turn off after a certain set amount of time? I assumed it does, givien the "non-latching" style switch(?) :wonder:

But... I haven't actually experienced it turning off at all (orange light never seems to extinguish) - i.e. it either takes a really long time to do so... Or it just doesn't! :confused:

Think it's on a timer as my '00 seems to turn off after around 10mins whether the screen is completely clear or not.

It is timed via a relay

I'll have to time it.

But I've a feeling mine doesn't turn off (if that's actually possible?).

Cheers peeps.

Update...

It DOES turn off! :) Takes c.13mins. on mine.

Er.... just thought I'd share that. :D

AFAIK, the one on my 98 car, (UK sourced) doesn't, I have to do it manually.

I take it, therefore, that it's a "latching" type switch on that car, then?

mine doesnt turn off, well, the light stays on the dash constant if i have turned the switch

"turned"? Don't you mean push?

How long did you leave it? Like I said, my one turned off after 13mins (not 10).

Mine doesn't turn off by itself, MY00 UK, latching switch.

joey, try leaving it for at least c.20mins next time (make a note of the start time). :)

I, like you, THOUGHT mine didn't work..... But it actually DOES! ;) 13mins.

No, I definetly have. My windows at one point were always misted up, due to leak in the boot. So I used to have it on constantly on most journeys. Unless it turns itself off after it has sensed the window its clear, which sounds a bit complicated for an old car.

Yeah, it's allegedly just on a set timer. Which, as you say, would be appropriate contemporary technology.

In that case then joey...... bugger! :(
