X308 cabin humid..Cleaning AC EVAPORATOR advice
Hello
My 1999 x308 4.0 V8 has a humid cabin after the AC is run.When the car is parked after a run, the windshield will fog up .
There's no coolant smell, nor coolant loss, so I'd say it's not the heater core matrix or its connections .
I think it's the evaporator not removing moist air , most recently I noticed only one side of the drainage pipes around the transmission expelling AC water. No wet carpet .
So my question is, how best to proceed , can the drainage pipes be accessed from the inside to check they're not blocked ,
Also I'd like to clean the evaporator fins, as it's possible they are clogged and accumulating water... How can I do this without dismantling the entire interior? Can I use an air compressor blow gun to flush out debris on the fins?
Any advice is most appreciated. My car is right hand drive, Australia, that nay impact in what's accessible.
My idea is not to have to dismantle anything preferably

That’s a classic sign there is water in the car. The side that doesn’t drain is the one that needs further investigation. You’ll have to look on the side (where no water is draining) of the center console and I believe you can pull the carpet down to see a black rubber tube coming from the bottom of the case and going into the side of the transmission tunnel. Search up a post that I started called “Evaporator time” (2018 or 2019) and I took some pictures that should give you more technical details. You can use compressed air inside the evaporator case. Just be careful of how you blow it out.

As mentioned. Classic classic water in the cabin floo rmats.Pull the side of the carpet away and look for the rubber hose what goes through the floor tunnel. Remove that. If there is blockage in the hose or where the hose goes under the car. You'll found out that straight away.
I'm about to clean evoporation core in my car in next couple of weeks. Clean without taking the whole dash out. I'll post my findings. I have LHD car.

Also , there was moist air do much that I briefly saw some mould take hold on the headlining.. So I plan ed some water absorbent crystals in the car to remove the dampness in the cabin air in a small container.
Initially I placed it in the drivers footwell, then moved it to the rear footwells...it only removed very small amounts of water. When I got to the passenger side footwell , it removed 100mls surprisingly .
It leads me to believe only one side of the drain system is blocked.
Fortunately there's no odour , seems i cought it in time..
I'll look and post back when 8 have result.

I spilled some water (a substantial amount in relative terms) in a rear footwell a year or two back. Beyond using copious towels and a hair dryer, I hung up a "Damp-Rid" bag in the car over the area that was still damp. The crystals inside (car closed up and in the sun) absorbed an astounding amount of water over the course of two or three days. All has remained dry in that back footwell and I now use a large box braced in the footwell to hold the bucket I use for flowers from the flower market every Saturday! Bottom line, that Damp-Rid product was quite useful to me.
