Stupid question about fogging windows

Mjolnir · 09-07-2011, 08:25 PM

So it's rainy today and I get in my car and the defrost. Big mistake. The windows fog up to the point of not being able to see a thing while driving. It takes 10 minutes to clear.

Advice on best settings to avoid this?

I don't drive mine often in the rain, but I had the same experience one time; makes for a few minutes of sporty driving in traffic! As I recall, the air came out hot, which I think made things worse, since it was warm weather. I figure I'll try it again (out of traffic this time), and experiment a little. I might try selecting AC, and the upper air outlets, see what happens. Could be the defrost button is for cold weather operation. As you can tell, I resist reading the manual. I mean, anyone can do it that way, but it takes a real man to drive into a wall while fiddling with buttons, at least my wife seems to think so. What they need to do is buy the GM HVAC system!

Use the AC (at any temp) with the air directed to the window

Turn on the Auto Climate Control and leave it on, and it will automatically stop you from fogging up. Your car has a 'mist' feature that stops the car from fogging up.

AC to the window.

Definitely the A/C

Yup, just leave it in auto with ac on at all times. That's what I do and I never have to touch it, rain or shine, hot or cold. Only thing I do is turn the wheel on the center vents from blue to red in the fall and back to blue in the spring. Find a temp that works for you (mine's 70) and you should never have to mess with it.

Would you suggest the diffuser attachment?

A/C removes moisture from the air, so no fogging.

I have had good luck with fog-x (like rain-x)
