That is essentially what I had, has the gauge on the top. I threw it away as it was empty, but believe i has color zones, green for low, blue for normal, orange for high, red for too high.
I couldn't get it out of the green, the can was also 3-4 years old.
How could you tell when your compressor was running?

Did you set the gauge for the ambient temp?
Was the compressor cycling?
ACP-100 Instructions » AC Pro
Check gauge pressure when the compressor cycles on. Rotate the black dial so the blue arrow on the gauge face points to the current ambient (outside) temperature on the dial. For temperatures over 90°F, point arrow to 90°F. If the pressure is below the range outlined by the “V”, continue per below charging instructions. If the compressor is cycled on and the pressure is in the red do not attempt to recharge, seek professional service. Detach quick-connect fitting from low-pressure service port.

Never try to adapt any of these refrigerant bottles to the "high" pressure side of the system. They wont fit anyway. You use the LOW pressure side of the system for recharging.
[QUOTE]How could you tell when your compressor was running? [/QUOTE]
Look at the front of your compressor when the engine is running, AC on, you will see your serpentine belt going round round on it's pulley, the front of your compressor has a clutch (inside that pulley), the clutch will be turning with the serpentine belt if your compressor is running (you can hear them "click" when they turn on) It will not run if your system is low on refrigerant. You will have to either use a jump wire at the AC relay, or a jump wire at your low pressure switch. When you manually power up your system, you charge it with your bottle on the low pressure side for a SHORT amount of time (like a couple 3 second sqeezes of the trigger) then pull your jumper wire out of the system and see if your compressor will run on it's own, if it does, reefer back to your bottle gauge and see how much more the system needs till full. Never hot wire your compressor and empty a refrigerant can into the system!!! If your not confident on doing ANY of this, or what I say makes no sense to you,TAKE IT TO A PROFESSIONAL...

Welp if thats the case it was not spinning. See video below.
So if its not spinning correct me if I am wrong.. #1 There could be no refrigerant or #2 Blown Compressor?

Did you check all the fuses? MY buddies D2 had a missing fuse, the black one with green stripe(I can't remember if it was under the hood or the Fuse panel inside) and once we added it the AC ran fine. Seems the PO removed it because the car was overheating.
If you cannot find a blown or missing fuse, you will probably need to take to a pro. As mentioned, if it needs re charging, where is the refrigerant going? I was trying to diagnose a friends AC and we ran 12 volts to the compressor directly for a second to make sure it engages. Not sure if this was the right thing to do, but I believe we ruled out bad compressor as it did engage, but no cold air.
Good luck, tell Yoda hi.

You gotta be in A/C mode.
And the econ has to be off.
ECON will kill the A/C compressor.
I would get a can of freon and shoot enough into the low side to get the A/C compressor to kick in.
You just add a little bit and wait about 3 minutes and feel the air from the vents.
It is possible to put in TOO MUCH freon and then the air temp will rise again.
Has to be a balance of just the right amount.
But Drowsap is spot on.
if your system leaked and you went to atmospheric pressure which means all the freon leaked out -
you need to fix the leak and pull a vacuum for sure.

Took a good look at it.
Removing the compressor and installing a new one looks pretty straight forward.
4 bolts on top, appears 2 hex bolts on the right side. 2 Bolts holding the refrigerant lines in place. Remove the belt.
Outside of that a pro can vacuum and recharge for what, $125?
