Do 4th gens have a cabin filter? If so, where is it located? It's starting to smell not so nice inside the car, thanks!

 

No....

 

No, but you could try cleaning out the gunk from the blower motor. Dust and other stuff accumulates there and it can start to smell.

 

Two area's to check.
Remove the air intake grill for the HVAC system. Under the wipers at the base of your windshield. And check for crap in there. Also check your HVAC ducts especially around the heater core, it could be leaking but not enough to drip on the floor.

 

Thanks for the advice, i'll check it all out. It smells like mildew/fungus then you throw exhaust fumes in the mix and it just smells horrible

 

Time for some frebreeze...

 

Or the evergreen hanging off the mirror!!

 

Stay away from Taco Bell.

 

I found a few leaves and other smelly debris around the blower, i cleaned it all out with some soapy water, sprayed some febreeze and so far so good!
