I just purchased a 2003 TL in Canada. I am finding that they front window defroster does not push out alot of air. I have checked the cabin filters, and have tried running it without them. Not any change. Any advise? Thanks

 

If you have a Navi, go through the ac controls on the screen and put the fan speed to 5, if that dont speed up the flow of air or if you dont have a navi, then check the condensor fan or watch the AC when its not selected to run the defroster because if it runs regularly when aimed at the cabin, should be fine when aimed at the windshield

 

it doesnt push out air like the front vents. Like how much does it push out compared to the front vents?
