Passenger side blows cold, driver side it’s cool but not compared to passenger side. I see a lot of people with warm air on drivers and cold on passenger side.

This is more than likely the blend door actuator on the driver side. Here is a guide that will help with this replacement:

Below you will find the process from the manual that will help with replacing this. I would also suggest checking the pressures just to be sure as a weak charge could cause this issue. However, it is more likely to be a blend door issue since you have dual zone temperature controls.
