Is there anything leaking? I know differential oil has a nasty smell, and not many people check the differential fluid levels (which may be low if it is leaking).
If it's that bad, and you don't smell it in the engine compartment, you may want to check your blower fan and clean the fan blades. I dropped the fan motor from behind the glove box, and cleaned the blades with Q-tips soaked in brakecleen. There was a lot of crap on those blades...
Then, change the cabin air filter. You have to go to the dealer for this one, as Advance Auto and the other aftermarket places don't sell them. It's bascially a cardboard piece with carbon black sprayed on it.
