(Re-syncing actuators) If you are having A/C air coming out warm on one vent & cold on other vents / or blend door issues, this simple fix is worth a try before delving into blend door motor replacement etc. Have done this & it worked for mine.
While car is parked. Start car & turn on A/C (Cold) WITH FAN SPEED ON MAX setting, run for 5 mins. Now turn to the highest (MAX) heat setting WITH FAN STILL ON MAX & run for another 5 mins. Return fan speed to normal setting & temp all the way back down. Now check blend door to see if fix has worked.

Thank you for sharing your solution... Hopefully, this method will save other owners $$$ from having to take their cars back to the dealership for servicing...
