The G/F is complaining of moldy AC smell. I took a look and see no drain tube for the AC anywhere sensible. Where are they hiding it? Its a 05 coupe 4 cyl.

 

Anyone know?

 

check your ac air filter

 

I know, I know
It comes thru the fire wall on the passenger side just above the rear sub frame.
Change the evaporator case air filter, then run the air on "fresh" to help clear out the mold smell.
Also when your girlfriend is almost to where she is going, shut off the A/C to let the Evap case get rid of extra moisture.

 

Hello
There should be, at the passenger's floorboard, a tube fastened to a hopper-like device (the evaporator) if it is like earlier models. If it is particularly wet or stinky near there and the hose will slide off (don't cut hoses) remove it and force air into the hose headed out to the firewall.Be careful using wire to unclog; don't do that if you are going to the evaporator side of the system.

I would advise spraying a odor knock-out spray or a Clorox/water mix (protect your carpet first) in the vents and the A/C intake near the windshield wipers. I had to do that a few times.
