This button, Heated front window?

[Dan1heMan]

Hi all, Ive just been doing some work under the centre console and this button I’m pointing at doesn’t light up when pressed, is it temperature controlled? As won’t come on unless it’s cold enough outside to warrant it? Or have I not clipped it back in right? It’s on a manual DB9.

Cheer's in advance!

As far as I’m aware, that should come on every time the ignition is on. Better check you connected it properly.

Cheers,
John
