Is it blowing but just not at the upper defrost vents?

Does any other mode blow air? Is the air not warm? Can you be a little more specific about "nothing happened"?

Are you even talking about the front defroster or the rear one ?

There’s a strong chance your mode actuator is stuck/failing. The dealer can test and calibrate them. Before mine failed, I was able to unstick them with a calibration one time. Mine was stuck midway.

Here’s an older thread related to the issue: copy/paste to your browser if the link doesn’t work.

That's a complete dash out of car repair.
Been there. $1400. Warranty paid $1300 of it. I opted to replace all actuators, even the good ones while the dealership was in it as peace of mind insurance.
I paid to have the working ones replaced. They only charged me for the parts. Thinking there are three and I paid $70 each for the other two.
