Thanks to everyone for your wonderful ideas of how to cope with the lack of heat in my car. I am pleased to announce that you need not worry about me any longer. Thanks to my cousin Derrick, my car now has heat. Apparently, when my other cousin installed the cd player he did a really bad job. So Derrick went in and re-did everything. What a champ.
If anybody ever wants to ride in my sweet, warm Hyundai Elantra, you know where to find me ; )
