If the heater has a sweet smell it could be that the heater core is leaking engine coolant. When the leak gets worse you will have a wet floor on the passenger side and the windshield will fog up when you turn on the defroster.

The smell that you describe is the smell of eng. coolant. If you turn your heater on to full max it will get stronger. Or, a cat slept on your car and you know what that means. Cat piss. It happen to me years ago.

Battery acid leak in car 2 months ago didn't know it was toxic and have been smelling fumes since then What should do now other than get a new car?

You should be able to clean it up if the problem is solved. Most batteries are outside the car- I wonder why you smell it at all. Battery acid is not especially toxic, but do not drink it, of course. I suspect that you smell something else. Could there be an exhaust leak or maybe the heater leaks antifreeze into the inside of your car.
