Front window demister

[sipaldi]

When I press the front window demister, as in heated screen, sometimes it works and other times it does not. Am i not understanding something? I don't mean the blower, just the heated front screen button. Initially I thought it was not working then I pressed it another day and it worked.....

It only works below 5C, which is irritating!

Ahh really, that would explain it. Thanks Craigy.
