The driver side A/C vents are not putting out as cold or forceful air as the two vents on the passenger side.

Hello,

This could be due to a faulty blend door actuator for the driver side.
The blend door actuator controls the hot/cold mix of air. Over time it can fail in a certain position and prevent the proper air flow.

The blend door actuator is located on the HVAC box behind the dash.

Here is a helpful guide:

I have attached a diagram below for your reference.

Let me know of any questions.
Thank you.
