The defroster in my Focus doesn't defrost the windshield properly. The last place to defrost is the area the driver looks out. The rest of the windshield will be completely defrosted but I have to wait for the area in front of the driver to clear up before I can start driving. I took it back to the dealer and they could not find anything wrong. They determined it was a bad design so I have put up with it for two years now. It is very annoying. I just came across TBS 07T08-S1 and I am going to take it to the dealer. I'll be interested in what they have to say.
