Anyone else have a window fogging issue?

steevr · 01-20-2009, 11:01 PM

Whenever the temp is below freezing and I've driven the car for awhile and then park my car to go into a store,etc., when I come out, the inside of all the windows are always fogged. We own two Lexus's, both with the Toyota Auto Climate control and never have this issue. Has anyone else experienced this with their Prius?

Nope, never here in Minnesota. Of course, I don't use the recirculate feature. Do you? Moisture from your own breathing will build up if fresh air from outside isn't brought into the cabin.

I love the power of the Prius defrost, even in our ol' antique 2004. Best I've ever had.

Set it on Auto, make sure the A/C compressor is enabled, and outside air is selected.

If I'm driving alone in the winter, I roll the passenger-side windows down a few inches during the last minute or so to exchange the dryer outside air with the more humid air inside the car. This reduces freezing on the inside of the windows while you're parked.

Hi,
I also have had this problem a few times. I agree with QBEE42 and Effwitt. Using the outside air intake and when necessarry opening the passenger widows a little does help alot.

I've found that this generally only happens when the temp is just on the cusp of freezing and and hitting - figures(°C). As mentioned above try to resist recirculating the air, I managed to freeze the inside of the windshield once by forgetting to switch off the recirc......

No, I've not had this problem. I'll play with the air recirculating system and try to duplicate.
The suggestions about fresh air etc seem sound.
