It will work for the cold and hot and speeds, but it stays on defrost mode. It won't blow through vents.

Is there a way to manually by hand, put this back into where it blows through the vents only? And not in defrost mode?

Or do I need to reset the fuse?


Thank you

Not really, the blend door is held by an actuator which you need to replace, (the mode blend door actuator) which isn't too bad to do.

Here is a guide to help walk you through the repair and check the images below so you can see which one it is:
