HEY I LIVE HERE IN RAINNY VANCOUVER BC AND I HAVE JUST NOTICED LATELY WITH THE WEATHER THAT WHEN I PARK THE CAR AT WORK IN THE MORNING THE WINDOWS GET FOGGED UP...I PARK THE CAR UNDER GROUND WITH (THE WINDOWS CLOSED). DURING THE NIGHT AND I HAVE CHECKED ALL THE MATS ARE DRY....NO WATER I HAVE EVEN RAN THE AC WITH THE CIRCULATE BUTTON ON SO NO OUTSIDE AIR GETS IN ...ANY IDEAS ...HAS ANYONE ELSE HAVE THIS..

 

Leave the roof down....just kidding. Although, maybe you should try lowering one window a bit to "normalize" the inside/outside temps. Sounds like a dew point issue.

 

sounds like you need to get rid of the horny girl in your back seat

 

ha ha never mind i just saw that you have a slk....no back seat sorry

 

ALL GOOD SUGGESTIONS BUT I STILL SEEM TO HAVE FOGGED WINDOWS..MY WIFE FOUND OUT ABOUT THE GIRL THOUGH HAVE NO PROBLEM WITH THE WINDOWS BECAUSE THE LAWYERS WOULD TAKE IT...

 

Usual cause of fogging windows (apart from the suggestions already put forward) is when the A/C evaporator drain is blocked.

You don't ident vehicle type...someone suggested SLK?...

S Class are extremely prone to the A/C plenum (air inlet) drain being blocked but it is usually the evaporator chamber drain.

Does the fog clear with the A/C running? with and without recirc selected?

I have a 2003 SLK-230

Whenever I start it up, the AC blows a HOT, incredibly HUMID blast for about 4 minutes.
It's so humid, it fogs up all the windows until the AC cools down and starts to defrost things.
(Oh, I'm in San Diego and it's "summer")

I suspect that the evaporator drain is clogged.

How can I get to it?
Does anyone know where I can access it?
From the inside? From the outside?
