a burning clutch more easily with the heat all the way up? today it was like 15 degrees this morning and i had to blast the defroster to get the ice off my windshield. i knocked enough off to be able to drive so i was driving a little with the defroster on full blast and smelled a little burning. my driving wasn't stellar this morning but i don't think i would have burned the clutch enough to smell it, wondering if it was the clutch or maybe something to do with the heating elements?
