I have had my car for about 8 months now which it probably has been cold 6 of them here in Oregon. I usually have to throw on the rear defrost about 2-3 times a week. Generally it takes about 2-3 minutes to completely defrost the entire window, but now for some reason it is ridiculously slow. I went to a movie tonight, and it takes about 10-12 minutes to drive home. I hit the defrost the second I started my car, and it wasn't half way done by the time I got home even though my car engine was heated up before then. Not sure if this is a known issue, or happens occasionally for some reason? Does anyone know what the deal could be, is there something I should check? I need this thing working for morning driving, so the sooner this can get fixed the better! Thanks
