hey guys, it's winter time here and my windshield gets really frosty. my fan settings all seem to work except there is not much air coming from the vents. if i put my fan on max (4) and turn the heat way up and make all the air blow out of the windshield vents, it takes a good 25 minutes to clear up the window very slowly. i can feel the heat near the vents and some air coming out, but just not enough. i don't think it is supposed to take so long to defrost. i've tried turning my A/C on too and it helps a little, but does not increase the amount of air coming out.

i've tried searching and read a bit, but don't fully understand the sword or maybe this isn't related to that. any ideas please??

thanks a lot!
