My car has the dual a/c feature that allows the driver and passenger to control air temp. Occasionally the system controlling the driver side will stop blowing cold air and will start to blow hot air but the passenger side will still blow cold air. Turning off the a/c and then back on again does not fix the issue. If the car engine is turned off and then started again, the driver side system will resume blowing cold air. This may last a while or sometimes it will only last a few minutes and then it will happen again. Sometimes it may not happen at all, but the only way to make it work again is to turn the car off and then restart.

Your HVAC system has two blend air doors. Based on the position of the blend air door determines if you get heat or AC. One door is for the passenger side and one the driver's side. What you need to do is check to see if the door is closing when you lose AC.

The blend door is located on the heater box, under the dash. It isn't easy to get to, but that is what needs to be done.
