This question already has an answer here:
My 2001 Toyota Corolla recently started smelling very foul whenever the air system was turned on. According to the research I've done online, there is no cabin air filter to change. The glove box seems unable to be removed, so I can't see behind that very well.
The dealership where I bought the car is not in the town (or even the state) where I live.
The research I've already done claims there is no cabin air filter for a 2001 Toyota Corolla, but I can't figure out why it smells so foul.
Can anyone give me advice on what action I should take? Also, if you suggest that I take it into some sort of shop, how much should this cost? At the Toyota dealership here in town, it costs $87 for a diagnostic.
(Note: The car smells poor because it's somewhat unclean, but there is a very distinct and very strong bad smell from the vents whenever the air is turned on. The smell comes from both the A/C and heat.)
