the a/c compressor kicks on when a/c is turned on, the fans and blowers work.
it seems to have the correct amount of R134. BUT no cool air comes out. i checked all the fuses and those where fine and the relay and that seems to be fine, it reads about 25 to 27 lbs when the compressor is on and cycles down some. but again no cold air. this eveing it was about 80 degrees and the air coming out at the vent when the a/c is turned on also is 80's. when i slide the dual climate up to hot it gets hotter like normal. any ideas and tips or something else i should check. i wonder if the climate control has failed in some way? by the way i just bought the car. i was told it worked fine last summer.
also blower fan wroks on all 5 levels

As long as your AC is on, pumping and filled at pressure with a correct ratio of juice, something should be cold. Check the lines. Maybe the condenser's clogged internally or externally and needs replacing too.
If nothing's cold it may be your compressor.
Your actuator doors are just that. They control where the air goes. Not if it gets cold.
The blend door actuator is at your right leg in the center console area under the radio. To get to it is very difficult, but it is 2 screws and an electrical connector. If you replace it make sure you put the switch to full cold or full hot.
I just replaced mine and my driver side still blows warmer air than the pass side. Still looking around to troubleshoot mine.
I would check the temperature sliders on the control panel as well. I just went through this a couple of times, I screwed up a slider changing bulbs in the HVAC panel, twice. The second time I did it, that particular slider would would blow room temperature air at it's full cold setting. It would go warmer in hot, but it would never get 'cold'. Everyone tells you right off the bat it's the blend door actuator, and it may be, but it is far easier to check the sliders first to at least rule that out. Just my .02 from my recent experience. Good luck!
