This has been an issue since I have owned this truck and living on the Gulf Coast in Florida it kind of matters a lot at this time of year, but my air condition just is not blowing out hard enough. Even wide open, I have tried to find a problem but I can't find anything at all. Any ideas would be greatly appreciated. I really need to get this fixed so I don't sweat so much on my way home from work at red lights..

 

It is usually a blend door issue when there isn't enough airflow. Do a forum search for blend door and you will find a ton of threads about it.
