Default 99 gs300

Hey guys,
I'm new to the Lexus team,
Purchased a 99 lexus gs300 and I love this car.
But I'm having some issues already.
I have lots of questions for you experienced owners.
My car blows hot air underneath driver side, and it doesn't go away.
Feels like if the heater was on. But AC system is off.
any help?

They call these servo motors on there cars. Every other car they are known as mode door, or blend door actuators. Common problem. You have one or more that are not functioning for the climate control settings. They are up under the dash. Many pics and info available on replacing them.
