I have no clue as to where it is or what the guy was talking about, but my friend was having the problem and I just caught that little bit.
That some guy knew what he was talking about!
This is the contributor to a stinky A/C, and interior leaks.
I discovered this when trying to track down a musty old-sock smell coming from my A/C.
In this pic, I have the A/C blower fan and moter removed. This is a simple process, as you only have to remove like 4 screws and it just comes right out of the housing.
The drain is located directly above the word "Fluid" on my washer tank:
If you don't feel like removing the blower motor, just pull the rubber boot off of this drain hole and scrap inside with a coat hanger.
You can see the junk that had built up, gotten condensation on it, then started molding to put off the foul odor:
Also, notice the rubber boot in the above picture. This covers this drain hole, so it may not be immediately visible until you find the boot.
Here's a close-up of the stinky crap. While you're at it, you may as well check your A/C condensor for the same stuff!
Ford's design on the A/C drain is faulty under most operating conditions. Centrifugal force keeps any condensation, rain, or whatever ends up going through the A/C induction vents to the rear of the blower box, on the opposite side of the drain hole. Over long periods, build-up forms from the small particles in the water, and creates this nasty crap like I had. After cleaning that off, my A/C smells good as new!
