The air works but only blows on feet and defrost, nothing comes out at the panel, even when I flip it to panel it still blows on feet and defrost. I started to take the controls out but I dont know what I am looking for. Thanks

That's the default mode when you lose vacuum. Check the vacuum lines from behind the intake going over to the passenger side near the PCM under the hood.

I just got finished fixing the same problem on my 07 trailblazer. It ended up being a electronic actuator that opens and closes when you switch from the upper and lower vents, not sure if the f-bodies have the same setup. I also have a quick question. I just recently put some fresh refrigerant in the camaro, but the A/C doesnt really blow that cold! Is this normal for f-bodies?

Trailblazer is a different set up, listen to the previous guy and check the vacuum source. Now, just because you put refrigerant in the car doesn't mean it will work. What kind of refridgerant did you use? Whats the low side pressure? Have a way to check the high side?

Yeah the low side pressure is good, the refrigerant I got from walmart, and I have no clue how to check the high side pressure. To give you a better idea of what's going on; the A/C works it's just not very cold.

there are many ways the a/c may have issues. Did you put in a new orfice tube? Why did you put in new refridgerant in the first place?

Thanks guys, I will first check the vacuum lines. Hopefully thats all it is I just had a new intake put on so Im leaning towards that.

OK, its def. vac. related. after doing some messing around. At idle when I turn the air or heat on the engine drops down to 500 or 600 til i turn it off then it goes back to about 1000. (I never noticed before because I was driving with the air on.) So I looked under the hood and didn't notice anything out of the ordinary? Any more suggestions?

i also and having the same issue,

if i find anything out ill be sure to post,
and if you find anything out please post it here also lol!

I got it, the people who did some work on my car failed to hook up the vacuum line to the back of the intake, the reason I didnt get it right away is beacuse I didnt reach down far enough I was seriously less than half inch away from where it plugs in. Easy fix though
