Does the driver side cool at all, or just blow ambient? It sounds like you could have an actuator fault, but you could also have a base HVAC system fault as well. You can enter diagnostics on your vehicle to display fault codes, and if you have an actuator fault, it could have a code. Start with key on, by pressing the info button up, and on/off at the same time and holding. Eventually(within several seconds) it should illuminate all display, and you can release the buttons. The info center will eventually read ALL, when it does, press on/off again. The display should now read ALL CODES, press on/off again. What will happen, is all codes from all modules will display, in alphabetical order by module. IPM is the module we are most concerned with at this time. Record the codes and reply to this post. If you do not get them on the first run, just turn the key off and start over. You can not do any harm, unless you execute a clear codes command, and that takes more steps.
