if the air from the dash is cold,
then ur compressor is still good.
if they're not cold, ur compressor is bad or ur just low on refrgiant.
if they're cold but not blowing air out of the vents,
u got some vacuum leak going on,
or maybe the AV control switch is bad.

Don't go investing in new AC parts just yet bud. Go to TUFFY or something similar, small auto repair shop and see if they'll run an AC check for free.
With my first cammy, I ended up replacing the accumulator, the compressor, and all sorts of goodies, upwards of 600 bucks. They installed it all, still didn't work, and then they replaced the switch, wow,it all worked. HAHA.
The switch is the thing that plugs into silver CYCLINDER that holds your refrigerant.
Usually has a HP and LP cap on it, usually to the left of your engine near the firewall. There is a switch that clips on to two prongs.
Keep reading to test your system at home.
There is one way to test if the switch is the problem.
Turn your car on. Turn your AC on FULL BLAST. And follow this test cycle.
1. Are the fans blowing? If yes, proceed to 2. Else it is the blower.
2. Is it cold? If not, proceed to 3. If yes, nothing is wrong.
3. So it's warm, which means either one of two things, low on refrigerant, or the compressor isn't engaging. Proceed to 4.
4. Keep the AC on and pop the hood. Locate your compressor, it is a COMPONENT (belt driven) where the two silver hoses from the refrigerant (accumulator?). Now, is the clutch on the compressor coming on and off? It's the TRIANGULAR shaped brackets on the compressor (front). When they engage, it uses the belt to compress the gas. Under normal operation the clutch engages and disengages based on the level. It should be either on or turning on and off. If it doesn't turn on, proceed to 5. If it does, your refrigerant is low or you have another problem.
5. You've gotten this far, and the clutch isn't engaging. Most likely culprit? The switch, to test to make sure the compressor works, locate the PLUG on the back on the SILVER CYLINDER. Depress the sides and pull the electrical plug out. You will notice two prongs on the cylinder. Take a SMALL PIECE OF WIRE, with ends exposed, and JUMP the two prongs. This will send the signal to the compressor to turn the clutch on. Do this while it's running and the AC in the car is on.
6. Does the COMPRESSOR CLUTCH engage? Well, if so, that's great, most likely your system is fine, however your switch is bad. If it does not, it may very well be the compressor or compressor clutch. You have at least pinpointed the problem to a single component at this point.
7. IMPORTANT. If you find the compressor clutch goes on, and you leave the wire on, go back to the car, and the AC is nice and chilly. DO NOT FREAKING LEAVE THE WIRE AND GO DRIVE AROUND FOR A FEW HOURS. I almost had an engine fire by doing so. The compressor clutch needs to engage and disengage during regular operation. It cannot stay on! PERIOD. GO GET THE SWITCH REPLACED! My serp belt melted, my compressor was bright orange, and thank god I noticed this before it blew up.
Take care and good luck!
