2010 F150,5.4 engine size driver side blows out cold air but the passenger side blows hot air, anyone can help me how to fix the passenger side so I can have cold air on both sides. Any help would be appreciated.

 

Most likely bad temperature blend door actuator on passenger side. When you remove it make sure the door is not binding in the a/c box.

 

Passenger side temp door. Behind the radio...
