For some reason whenever i have my a/c on during the day or night right in the middle bottom section of the windsheild water condensates on the outsid eof it.. i use the windsheild wipers to get it off then second later aother circle of water on the outside. its prob just a real rough estimate six inches long by 4 high oval shaped.. i took it to the dealer and of course it wouldnt do it there.. it does it majority of the day and every single time at night. any ideas?

sounds like condensation....humid where your at....maybe its constantly blowing cold air out the defroster when its not supposed to...just throwing guesses out there....maybe not your a/c at all, just a faulty windshield....

Yes its condesation.
The defroster runs the AC but does not
turn on the AC indicator.
Its been humid here in the central
states and does it daily for me.
And I just thought it only happend to me.

On my trip out of town this morning for work it did that when i turned my defroster on, my windows had actually frosted up some over night, even though its like 80 degrees outside. When I was driving my windows started to fog, so i turned my defroster on and 3 small (3" x 4") ovals appeared lower center on my windshield... but they went away after a bit.

Defroster = A/C compressor running.

Completely normal. Every car can/will do this. The windshields just getting so cold, and its warm outside. just like with a can of pop gets condensation on the outside. Move the temp dial slightly towards warmer once air temp in car comfortable.
I notice if I use a mix of floor and vents this doesn't happen. But if I use just the floor or defrost it will.
