weird smell

[B 4 You]

so i got my car inspected tonight, the people were really nice, and they fixed an exhaust leak for me for free so i would pass. but then when i left i noticed a really weird smell coming from the defroster. it's not gas, it's like a chemical smell. i don't know if it's bad or not, it's just weird, but only the defroster, not the heat or anything else. is this cause they fixed my exhaust leak? or something they do when they smog check a car? i'm not sure, but i don't like the smell. it's kinda gross.

Does it smell like burning coolant?

i don't think so. i had that problem a year ago, it smells more foul than sweet.

and i drove my car earlier with no smell. it was just after they inspected it. i think they cleaned something out or used some chemical in the test and it's just residue. it makes me a little nauseated.

well i drove home from work, and the smell gradually decreased, so i think it was residue from something at the shop. it almost smelled like metal, which would make sense since they welded the exhaust.

Sounds like its nothing to worry about, unless it comes back. good luck
