Since I bought the used car in 2003 I found the car smelled sweet, antifreeze coolant inside, but I thought it was normal for the car. But in Feb, the burning odor became stronger especially when I turn on the heater. Now, the front interior windows become fogs up right away whenever I turn on the heater or just driving. The odor is getting me sick, and the windshield is so fogged that I need to constantly wipe it just to see out. I think this is becoming unsafe to dirve.
