A/C not really cool...

[DallasTahoe]

As summer approaches I rely on my A/C, but its not blowing like it should, or atleast like I think it should. The rear ac blows cold, not freezing but cold, while the front blows almost cool, and that's no matter how I have the ac running. I tried the ac cleaning in the tech section by 2drhoeon4s and it helped I think but it still doesn't cool like it should. Last year I had the orifice tube changed and the system charged, it still works like last year so im wondering is there something I can do to get it to work equally as well in the front and back or am I just stuck?? Oh btw I actually did a small mod by adding two a/c vents right above the driver and passenger seats and they work great!! but I still want the front vents to blow cold... any help? anyone? please?

sounds like the system lost some refrigerant. YOu can take it to a ac shop, have the system Evacuated and recharged to spec with dye so if it stops working, you can trace where its leaking, or you can go to a autostore and buy one of those ac refrigerant in a can and charge it up yourself

evacuation is not needed unless you are opening the system or suspect moisture in the system. and dye can be injected on a charged system.
