Help - GS300 2003 A/C only blows out of defrost vents
Hello,
I own a 2003 gs300 sport design and it is currently only blowing the a/c out of the defrost vents by the windshield.
(a tiny bit from two front vents directly by each door, and zero from center two front vents as well as center console back seat vents)
It makes the car take longer to cool down, though the air does come out very cold. It also makes the very cold windshield collect a huge amount of condensation from the humid air here in Central FL and makes it difficult to see out of the windshield when it is running for a few minutes.
Would anyone have a solution for this issue? What it could possibly be and if there is a DIY solution. I just want the AC to blast out front vents.
Thank you,

Background:
The AC was replaced about 2.5 years ago. During that I learned the temp control(?) was broken, and will take a long time to switch to cold if turned to hot. So I keep it set cold. Also would sometimes hear a loud vibrating(?) sound coming from inside dash, possibly an electric motor for the vents?
The engine (2jz) was replaced about a month ago (heads and block only w/ new spark plugs and wires) AC carried over to new engine
Only Now since getting it back I am having this issue.

Advanced
Yes, there is a servo that controls where the air comes from (feet vents, defrost vents, and normal vents on the dash). Sounds like the servo might be gunk'd up and needs to be regreased with dielectric grease. As stated above, search.. you can repalce or fix. I decided to take all my servos out and lube them up instead of spending for new ones.

Do check the if you gas pressure level is good? Because you say; AC carried over to new engine
Only Now since getting it back I am having this issue. You ac unit maybe, maybe have a leak somewhere. I my case, my a/c pressure was low on gas and make the A/C just blow hot aire out. Check that first please before you expend extra money and time on it.
