Back window always fogged up

[mschiavoni]

this is my first car w a recirc air option

I'm getting the same problem now. Probably from the snow falling inside the trunk and melting later. I used my defroster in the back, and got the water to bead up on the rear window...so I wiped it off before the car got cold again.

Products like No-Fog (From Rain-X) seem to help a little bit, but the glass has to be perfectly clean or you see streaks of a filmy substance when it tries to fog up.

I like to get my car nice and HOT in the winter then open the windows a bit. It makes me THINK im drying out the car, at least.

Opposite effect for air conditioning (cooling) than heating, as recirc will cause humidity from people & nowhere for it to go: The recirc/AC is supposed to dehumidify the air - the evaporator core will condense water on it & drip to a drain (not sure on KIA if its a drain or not). Also, you should have the A/C on non-recirc until the air gets cooler than ambient temperature, then as soon as the air gets cold, turn on the recirc; you're dehumidifying the air and also cooling down cooler air from inside the car, rather than 90 degree hot air from outside (and bringing in humidity). Tiny bit better economy with this method.

One thing I noticed is that with the exaggerated slope of the rear window, that when it does fog up it becomes very difficult to see out even with the defroster on. Even with a clear window, I feel the Koup is a difficult car to back up in. I do remember this point being made in a online review somewhere. Anyone else share this thought?

Never thought about that. Now that you say it, yes! VERY much so.

No issues backing up in my Koup, then again I drone tow truck for 2.5 years and didnt have a back window I could see out of most of the time anyways.

Sorry, I know this thread is old. My fiancé had an 02 rio, and now has an 09 sportage. I have an 09 spectra, with my dealer trying to find me the perfect koup sx! All 3 have had this problem. I have always assumed it had something to do with Kia lol.
