How quick are peoples rear window element demist? Mine takes quite a while it seems, but it might also be a fogged up second window, i'm actually looking at!
I did do something really dumb though...I for some reason half closed all the dash vents ages ago, and totally forgot. Stupid since they are right in front of you, ....And I was wondering recently, why aren't I getting enough warm air in here.
DURRR.. Opening the vents might help!
