Guys need help on this one.
When i turn my heater on cold or hot, a/c on or off, i get a really funky smell coming into the cabin.
Does anyone know what the problem could be. thanks

Common problem.

If it hasn't started to smell like urine, it will soon.

here ya go

Do a search on urine. FOR REAL. Couple of posts on it

That is definitely the cabin filter, get it changed right away and you should be good.

Thanks for the quick replys guys.
Does anyone know where the filter is located, plus how many filters are they for the cabin. In england i think they are called pollen filters.
