You need to change the driver side temp/blend door actuator. It is the bottom one under the center dash. Just over right side of center hump. Very simple, Do not plug the connector back in the new one until it has been installed,(mounted).

THE AIR DIRECTION VENTS ARE BROKEN under the steering wheel you will find a plastic cover with 4 screws, remove it and change the direction of the air manually, therewith you have to purchase a new AC control system

Wow really, not the LH blend door actuator. Read his response from last year, hope it's fixed by now.
