Appreciate any comments
It might already have been mentioned and by itself it shouldn't impact cooling as negatively as you're seeing but it can't hurt to check whether the outside air flap is closed when AC is running.

If you have the same setup as the Gen I (I assume you do since the early Gen II didn't have the passenger side airbag yet) then the way to check this is by either pulling the glove compartment (easier to see)or popping out the little grey plastic oval in the back of it.

Shine a flashlight in the opening. See pictures which show the open flap (lets outside air in) and closed (recycles cabin air -hence colder). The flap is the part with the deteriorating foam on it.
