Has anyone kind of had a loose driver window? It works fine going up and down, but whenever I push the button to go down and let go, if I push down on the window itself it moves maybe another half inch lower. Wondering if I need to tighten something on the window itself?

 

take the door panel off and check the regulator.

 

Agreed. Two screws attach the bottom of the window to the regulator slide. Make sure they are secure and the pulley line itself isn't loose.

Also check the window slides for tacky or dry lubrication. Some WD40 specialist silicone lubricant can ungunk window movement.
