I've solved it. Lots of owners are complaining of really cold air emanating from the driver's quarter window in the front with a strong draft. I noticed it too. The solution is very simple. Put the front blue defroster on and it goes away. Simple as that. No more cold air, no more draft. How that does it I don't know but it does. Try it, you'll like it! It really works! Saves a trip to the service shop.
