Guys I noticed on the TSX that the top 3 horizontal lines on the rear windshield does not defrost...as per the dealer and TSX forum these are the radio lines and so it does not defrost. It leaves an 8 in "non defrosted" strip of windshield on top limiting visibility, which annoyed me. Does the TL have this characteristic?
I mean my antenna for the radio is integrated in the rear windshield on my BMW and it cleared up the whole window. Curious because in a couple of weeks I should be getting the TL

 

As far as I know, the only area on the rear window of the TL that does not defrost is that area hidden by the third brake light.

 

use the defrost liquid from RainX. I happened to find one at my pepboys location. ITS just great. I mean the entire winter is over, and i never ran the defrost on front/rear windows once.
