However, it does blow out from the windshield and from the bottom.

Hello,

It sounds like you have a faulty mode door actuator.
The mode actuator controls where the air will flow from. It can go bad and get stuck in one position.
The mode door actuator is located on the HVAC box behind the dash.

I have attached diagrams below for your reference.

Let me know of any questions.
Thank you.
