Hey Guys,<p> I tried searching the archives, but came up empty. When I first test drove my car, it was actually an S40. I had 4 guys in it, driving up a snowy mountain road. Car was great, but I found the defroster was barely able to keep any of the windows clear. I didn't think too much of it, but when I got my V50, I noticed the same thing on the first night. 4 of us in the car(3 of us a little intoxicated!), and the poor DD could barely see through the windshield.<p> I called the dealer today, and asked if this was a problem. The answer I got is that it is caused from all the new plastic, vinyl, leather and other materials out gassing from the vents, and that it will be better in a month or 2. Now, I own an auto upholstery business, and I do understand outgassing, but I've never seen it become a problem for the defroster.<p> Anyone else have this problem?<p> Al

Yeah, I often get the foggy windows, but I haven't though that it is a particular problem. I usually drive alone, so the defroster works fine for me. Just be sure that the air is coming from the outside (rather than having the inner-circulation mode)<p>Well, personally, I do not think what the dealer told you will be the solution. Is there any anti-fog treatment from Rain-X? Maybe it could help.<p>I think that S40 has a low visibility - it has thick pillars (which might enhance the safety of the car), small rearview mirrors, and the "foggy windows".. but definitely it is better than Hummer.. hee hee..

Re: Foggy windows? (Al Canuck)

Never had problems like that, and I live in rainy/humid place <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0"> Set up air circulation to AUTOMATIC. Should be okay.<p>The diler talk is one big BULL... He should tell you how to "manage and control" the A/C.<p>BTW, do u have electronic climate?

Re: Foggy windows? (tomi22)

Just flick the air con on - 4 blokes produce an awful lot of moisture in an enclosed space. I find I usually have to put it on if I'm wet or if the humidity outside is quite high.<p>I have to say that the fogging has got less noticebale with regards to gassing off - the haze on the wwindscreen doesn't build up as quickly any more.

Re: Foggy windows? (Marmoset)

Thanks for the input, guys. I've got auto climate, and had the a/c on, fan blowing like mad, and we even cracked open the sunroof a bit. Still foggy as hell. I'll see it goes over the next few weeks. Now that I think about it, there was actually 5 of us in the car. 3 guys, and 2 girls, plus, we live in a damp area. Still, my old 5 series never figged up with 5 of us in it. Oh well, I'll wait and see.<p> Al

Re: Foggy windows? (Al Canuck)

Especially in the V50, moisture can be an issue. Don't be afraid to use the "Defroster" button, which turns on the a/c compressor and blasts the windshield. You can hit it for a minute or two, then touch the big "Auto" button to return to normal.<p>Another time you'll want to use defrost mode is first thing in cold weather, or cruising in very cold (0F) weather. The auto-climate works so well in most conditions that it's easy to forget it needs a strong hint every once in a while.<p>The only thing I wish is that the defrost button was REALLY BIG and REALLY EASY TO FIND. I have to hunt for it every time I truly need it. It's the one slightly disappointing thing about the instrument layout I found.<p>Tom.

Re: Foggy windows? (Pez)

See, that's just it. We did have the defroster on, as well as the rear one. Rear window cleared in about half a nanosecond, but the front one simply couldn't keep up.<p> Al

Re: Foggy windows? (mullmann)

Yeah - you weren't all, like, breathing or something were you?<p>Seriously, you might want to ask the dealer. There are calibrations and the like. Are you satisfied that the a/c is working properly?<p>Tom.

Re: Foggy windows? (mullmann)

Foggy windows and late model s40/v50s? I noticed this as well. In fact in my 18 years of driving 9 owned cars and dozens of rentals, got to say my V50 gets the most fogged window award. yeah, if climate control is on constantly it'll be ok, as far as new materials letting out gases etc, which may contribute to this, if so it will probably go away but when ??? after 25 years. let's just face it Volvos get fogged windows very easily. never got passionate in my car but then again as a child I was affaid of that movie "The Fog"

Re: Foggy windows? (tomi22)

OK, if the cabin/pollin filter contributes to this, how often should we change it? and will changing it help at all?? my volvo fogged up on day one. to me it seems like Volvos fog up and Corvettes have pushrods , how can we fix the problem??? I've learned to live that my Volvo fogs up very easily. I'm almost at the 1 year mark.

umm.. if I am looking the bright side of the foggy window, it might help to keep privacy so that we do not need window tinting.. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0">

Re: (overture1928)

Another thought Al, check for leaks - might one off somewhere in the car but it's gotta be a big one to fog up all the time, my wife's MGF was awful until I managed to stop the leak...

Or, non-leaks. If the drain pipe from the a/c evaporator is plugged, this can cause excess moisture in the blower. The sunroof drain is another popular location, it can end up in the rear passenger footwell.<p>Tom.

I've always got my vents pictogram set at Head and feet, to remove fog and keep toes warm. Head only works great too at cold startup without having the a/c compressor kicking on. <p>defrost is just head (front vents) with A/C on max. I consider it a short cut for emergency use. it's the be-all end-all defogger, not something I need going when I'm driving across Pennsylvania's I-80 in a snow storm.

Ive used Rain-x on my windshield and it has done a pretty good job so far. Its a little foggy still but not nearly as bad as its was before. So Rain-x seems to be at least a temporary fix..

Re: (cbeerxx)

Lots of interesting points, thanks. <p>1) Cabin filter - First time my car fogged up, it was 8 hours old, and had 170km on it. Doubt the filter needed chaning!<p>2) Leaks - Again, 8 hour old car, and it had not seen rain while I had owned it so far.<p>3) Volvo's just fog up - This seems the most plausible, although I've not seen it before, and it seems more than a little irritating in a $50k car! Plus, this was a dry, cool night. I can't imagine it on a cold, rainy one. This thing definitely has a problem, although the A/C kicks in nicely. I'm going to clean the glass frequently for a while, and see what happens.<p> Al
