now that it is getting cold up in here in Mass. i have noticed a strange smell when i turn on the heat. this happened only twice so far. the other day and maybe two months ago. both times it was when i was running the defroster and had it at the highest power right ofter starting the car. it stays for maybe a few minutes no more than 5 minutes. it is not a burning smell or at least it doesnt smeel like it. i dont no how to describe it. it is awful causing me to shut it off for a while and then it is gone. anyone had this happen and no if it is a problem wit the car or just a freak thing. thanx
