have any of you guys had this issue when it rains or when its really cold out?

ive been trying different things to see if there is any effect.
ive tried full blast heat and the sides and the rear will fog up really bad.
also tried full blast cold and has the same outcome or worse .

Only way that i could get all the windows to clear up 100% is i would crack the windows about half way down and run the heat to the front windshield.


i have had a new front windshield installed on the car but this problem has been doing it since i bought the car.
the rear seal hatch glass is new. the door seals i do know i need to change . and the blower motor is working properly . im getting the new door seals next week i hope that is all i need to fix this . but it doesnt seem like that is the whole problem to this .

any help would be greatfull guys
thanks guys.

 

i used this stuff, cause the same thing was happening to me..except i have no heat or a.c. worked great for me.

Just wax your windows. I do it, and water beads off the outside like rainx, and the insides don't fog.

 

I always use the defog setting and the AC. Worked OK back when I still had freon.

 

clean your windows man. this is the one thing most people forget about when washing their vehicles. it takes only a few minutes, and a bit of elbow grease if you've never done it, or if you smoke.

if you don't clean them, dirt gets in the pores and the dirt attracts the moisture deep into the glass. that's why they get so foggy specially when it rains. after you clean the outside windows a bit of rain-x or spray-on wax (just follow instructions carefully) will work great at making a protective layer and sealing the pores so the dirt doesn't get trapped in there, just remember you WILL eventually have to do this again because it wears off.

here are a few tips on how to properly and "professionally" clean your windows if you've never done it.

when you clean your windows do it in horizontal lines (the human eye has a hard time seeing horizontal streaks) and always use a clean side of the towel per window. I like to fold the towel in half (a soft terry cloth will work fine) and keep a dirty/wet side and a clean/dry side. fog enough cleaner on there to get the window wet, clean with dirty/wet side until most of the cleaner has been absorbed into towel, then immediately clean again with clean/dry side until all water/streaks have been removed (you may have to repeat this several times depending on how dirty they are or if you smoke, which you may stop doing after you see all the yellow grime it leaves on your windows). when the towel gets too wet, simple fold the towel the other way.

also when you do the inside of the windshields try to do it all at once, or else you'll have that horrible vertical streak right down the middle of it (very noticeable when you face the sun). the outside of windows usually doesn't streak bad, so its ok to do it in halves.

 

+1 ^^^ uncleanliness on glass helps foggy water to stick. Clean glass fogs less.

 

the 7's windows are very prone to fogging. using the defrost with the a/c is a very good way to keep it under control. fwiw, i keep my windows clean inside and out and it helps but they still fog when it rains.

 

any car will fog when it rains, unless your car is 100% air tight but with clean windows it's just the surface dust, and nothing that a bit of defrost (hot or cold) won't take away in less than a minute.

 

Make sure that you are drawing in fresh air, rather than using the setting to recycle the air that is in the car.

Also, make sure your heater core is not leaking, as this will simply produce more fogging very quickly. Does it smell like maple syrup in your car?

making sure the windows are clean inside and out is a great first step. however, if you don't have a working A/C, then use heat on the defogger/defroster setting. that has always worked for me. opening the window probably would work as well, but i'm kind of **** when it comes to letting water in my car, so i'd rather suffer with the heat on.

 

I have found that the defogger setting sucks big time on my SA. Its not the power but the vents just blow on the bottom 1/16th of the window. My solution is to turn the settings to vent and aim the center dash vents straight up and towards the driver side. The side vents point towards the side windows. This defogs way faster and way better than the defog setting on the controls

 

update : well was digging around and found some more causes that was making the rear glass fog up fast. the leftrear glass the seal is wornout( missing a huge chunk at the rear of the glass so im going to replace the seals on both sides.

i am getting that maple syrup smell in the car. wouldnt hurt to get a new heater core.

ill clean the glass better with that rain x product. im thinking the heater core is on its last leggs. its still raining here and i put a temp gauge to the vent and its not pushing a lot of heat temp wise. its pushing about 68 at best. the a/c is disabled but still has the refrigerant in it.


thanks for all the input guys ill try those out.

 

Trust me, if you've got the maple syrup smell then leaking coolant is going to be your biggest issue (and possibly 100% of it). That stuff gets on the inside of the windshield and leaves an oily residue that you can't hardly even see through. Yuck!

Rather than getting a new heater core, you might consider this option: Grab a bottle of Alumaseal Radiator Sealant, and dump about 1/4 of it into the radiator. Drive the car around with the heat on highest setting and within anywhere from 15 minutes to a couple of hours the issue should be taken care of.

I've been running Alumaseal in my motor for the last 17,000 miles with no ill effects (no clogging or any other horror stories you might have heard of). This is because when I installed the motor, I found that it had bad coolant seals, and was pumping all of my coolant out the exhaust pipe. This stuff cured the motor within 30 minutes, and I now have zero symptoms of any type of coolant seal issue.

Here's another technique that works for me, living in Seattle with no AC. If you have a sunroof, vent it all the way and set to high heat and defog. Water won't get in (thanks for that, Mazda), and your windows will clear up in no time.

Fix the heater core first, of course.
