If it is the filter, wouldn't hurt to turn the air on and spray a bunch of lysol in there to reduce existing bacteria/odor when you have the filter out.

 

 

i changed my filter but it still smells bad. could it be that da car needs more freon?

 

your not going to smell freon coming out the vents...

 

Sounds like you have mildew/mold in the system. Change out your cabin filter for a charcoal filter, get some Auto-Vaccine, run it through your car, and it'll smell like new again.

Only problem is that your car will smell like a freshly shocked pool for a week, but it's fine after that.

Be lucky that we have filters. I opened up my soon-to-be-father in laws blower motor in his 97 Sentra. We found a dead snake in the impeller, looked like he was chasing a mouse through the vents and got stuck.

In all fairness, the car WAS sitting for 10 months, but I've swapped all fluids, plugs, and given it a thorough detail. Who wants a freshly detailed Sentra GXE?

 

Most definitely the cabin filter. Get this one, its amazing:

 

If you are smelling freon...good change your gonna die from inhalation.

 

Any pieces of poop laying around in your car?

 

Hahaha, wow. I don't even know what I'd do in that situation. Looks like he sold his Coupe. Hopefully the new owner never finds these pics.

 

Ok that is just insane, I cant even put together a sentence for that.

Secondly. In Cabin air filter and somethings dead in it I bet.

 

Definitely the filter.

 

rotten egg smell is what i hate from a car lol
