Yup you guys are right.
Today i started the car and came out to check and it was still open. Came back in the car and actually heard the flap close. Came out to confirm and it was closed.
Liang, i had it unplugged but had to bring it in to the dealer for some warranty work and plugged it back in just in case they try to blame the problem on the unplugged valve. Started getting cold so i didnt bother. It's getting unplugged as soon as the temps get in the +
