I had gone to my 1998 GP GT today and turned it on to let it heat up as I cleaned the snow off and when I went to get into my car, the interior was filled with a fairly thick layer of smoke and smelled of some burning rubber/plastic but when I went to look for it, I found nothing that immediately stood out in the interior and under the hood itself. I had the back defroster on and the front defroster on 5. Now no air comes out when I turn it onto 5, only 1-4, what should I do?
