Everytime i turn on my car, the air vent goes to recirculation mode and i have to switch to outside air. Happens every time when i turn it on. Is there a way to keep outside air every time i turn on the car?

 

Yes, there is. I reset mine that way. But now I don't remember where I found the instructions. They were on a page in the manual or a thread that allows you to test all the ac sensors and functions. You'll have to search for it. As a remember there is not a specific setting that does this, but somehow during the testing precedure the default can be set. Sorry I can't be more helpful, but at least this is a clue. Maybe someone else knows where to find the test procedure.

As I remember to reset the default I had to stop the test when it hit the right mode. You'll have to play with it.

 

Same thing has been bothering me.
*Hint* if you keep the temp at ~3 or 4 clicks past halfway, it will stay on outside air.

 

This is good information- Will need to run the diagnostic.
