Has anyone else noticed excessive interior condensation in cold weather? It has been rainging for 2 days here in California, in the 50's and high 40's and I notice that when I come back to my car, there is so much condensation on the inside of the windows, it looks like someone has been making out at the drive-in. Has anyone else encountered this same thing? I have a 2007 E350.

Thanks,
Rick

My boss gave me a "seattle's common knowledge", it actually works very well. (RainX anti fog works, but it can be very oily and messy)

(ONLY if you do NOT have tinted film)
1. clean inside of your window w/ Windex (original formula)

2. get a bucket of warm water say about 2 Quote.

3. add 2 shot glass of vinegar (ask your wife for permission)

4. use lint-free clothes and massage the solution on your glass.


That's all to it~

p.s. it also works on your bathroom mirror!

sounds as though youre heater core may be leaking coolant or something. the
warm, moist air is coming out of your heater/vents and condensing on the cool
windshield after you leave. how is your coolant level? check clues e.g. oil
cap, dipstick (if you have one), whether you need to fill radiator more frequently,
.....or if this is simply outside rain water somehow making entry inside. how
about this: say the windshield is clean and dry when you enter...and you
flip on the fan/heater. does it fog up your windshield for a few seconds or
minutes?

Raymond, stop scaring me!!!!

It is normal unless you keep a car in a garage. Too much day night temperature difference/ Climate control of E class is really good in few minutes everything will be allright as only you start a car. Heated seats are a must here.

My car has been fogging up quite a bit down here as well in OC.

I just turn on the defroster and in a matter of seconds the whole car is clear again.

I think its just the humidity and the inside car temp and the outside car temp causing it to fog up more than usual.

I get the same thing too but its the humidity that builds up inside the car just like sunkist mention. Its normal ....

i listed some of the worst case scenarios above based on my experience with
other vehicles...as well as a pragmatic view of cause/effect, given environmental
conditions. specific to MB, it occurs to me that MB has a well known problem
which doesn't seem to be reported as much with other vehicles: odd smell
eminating from the hvac system. this is inherent in the design and is caused by
excess moisture which collects within the condenser and then fungus/mold occurs.
i'm wondering if this excess moisture may be lending to the condensation you
guys mention as being normal ?

yet, do not discard the worst case scenario as well, ie leak in the hvac, or
water intrusion from outside....simply becase the OP said "excessive interior
condensation." i've seen the conditions so severe that when this occurs,
and the temperature overnight is below freezing, ice forms on the inside of
the windshield. the $#% is having to scrape, melt this off before you can
drive off.

blah blah blah.... in the end, if the condensation found is easily eliminated
through use of the fan for a minute, then no big deal. if it requires wiping
plus fan for several minutes, I'd have the dealer take a look.

Make sure you turn off the charcoal and interior recycle features as this will make sure your car fogs.

Must be a west coast thing, never had that here in the DC area, though car is garaged 95% of the time....

Heated seats are a Must in Cali?? It was 16 degrees a couple of days ago here on L.I. ...at NOON!

chicks dig heated seats

HELL ONA HARLEY

Come-on barry and give the guy a break... Its common knoledge that it can get down to the 30's here... lol

All bull****ten aside, I would never own a car without them...

sunkist

Heated seats are a must...granted we wear summer clothes under our wintercoats the leather seats feels quite cold in my t-shirt and jeans at night lol!

I'm just jealous.

What's happening in you car is nothing new. That's what happens when your home / car is so well sealed that humidity cannot escape and the temps on the inside are warmer than the outside.

It also may be caused from a particular baffle that may be stuck internal to the ductwork somehow...Mine had that fogging on the right side only in the mornings.

I used to have an MGB that suffered from this problem and it was caused by the drain holes for windshield rainwater being blocked and water collecting in a reservoir before being drawn into the heater system - result was instant condensation after parking the car when the heater had been on.

Have the same issue with my 300SL, but can't find the drain holes.
