I had a tad bit of frost once and fog a few a times it worked fine. Fog started to clear up about 15-20 sec after I turned it on. The frost took about a min or so.

+3. Chi has had crappy weather. Obviously it won't melt an inch of snow quickly, but it melts the ice just fine. Get it checked out.

Koz is absolutely right, the defroster on the IS is pretty weak. I live in the D.C. Metro area, so it gets pretty cold. When I go to start my car in the mornings, the rear window will be completely foggy, turning the defroster on will have zero to little impact on fog/frost. It takes on average of about 10-15 minutes for the defroster to do its job. thats just WEAK, I mean the side mirrors heat up real quick but for some reason the rear windshield does not get heated up.

I don't know if there is unit-to-unit variation in defroster performance, or just in expectations. With a thin coating of frost on my rear window, the car takes no more than a minute or two to start forming a zebra-stripe pattern - with clear areas near the wires - giving enough visibility to see what is going on behind me. It takes about 10 minutes to finish the job. Not as powerful as the rear defroster in some other cars I've owned previously, but not terrible either. Compared with my seat coolers which truly are so weak as to be useless, my rear defroster is superman .

Works great for me with ice in CT

Mine has been fine up here in snowy icy Toronto. You guys getting the same huge snow storm that we're getting now?

To help prevent a "foged up" rear window, do the following:

1) Always use "outside air" when running your heat or a/c

2) Clean it with glass cleaner once a month..

Mine works fine, although it doesn't see any ice or snow in sunny southern California

Did you have the dealer look at it?

Koz

Next time I go in I will have them check it. I drove (25 min ride) to work this morning with the rear all fogged. It did absolutely nothing!

I'm glad to hear some work OK. Now lets see if the Stealer can fix it.
