right after the A/C off, the fan belows bad smell air of my 5th gens. Is there anything that i should have cleaned up?

Thank you

 

you have rotting water in your system. from now on, 5 min before you turn off your car, turn the fans on high to get normal air to dry everything out.

my friends lexus did this, and it took a while to get rid of the rotting egg smell to go away.

 

turn of the heater for 5 to 10 min.. it should dry out the water.

 

mine smells like ca ca too

 

I've heard of guys using a whole can of scented Lysol in their blowers under their hoods.
I think they put their heaters on and spray the Lysol in the blower, with the car on.

 

they sell stuff u can spray into ur vents to kill fungus

 

also check the drain hose on the bottom of the evap. box, there's a blk hose that drains out the water in the evap. box, if it's clogged or blocked from a floor mat for instance the water can't drain and it will cause your smell problem. The best way to rid this problem is to buy a new evap. box with new foam insert. At the dealership we do that or we use a chemical that you drill a small hole into the evap. box or you could shoot it up the drain hose, it kills whatever fugus is growing up in there. In my experience it always comes back though. Replacement is the best way in my opinion.
