86 AC Quit
Was working fine, then over a few months it slowly lost cool air and now it stopped working. I have a replacement coolant but didn't want to add more then it needed because I know that can ruin your system.
My pressure is within "green" PSI range when I connect the bottle to get a reading.
Also heard clicking coming from the compressor for a few seconds when I last had it on.
No clue how to proceed, when I bought it the previous owner had put in a new compressor and it worked great, less then a year ago.

spit in the valves and look for bubbles sound like your low on freon. don't believe the idiot gauge. valves can be replaced without looseing freon.

Your A/C buttons will help with a simple diagnosis:
Push and hold the fan up, and fan down buttons, until a number (code) is displayed.

But your pressure reading is only valid if the compressor is running. If it is clicking, the compressor may not be engaged. If the compressor is not running because the Freon (charge) is so low, then you might only be reading static pressure of the system.
If the compressor is not running and the fat pipe is not cold, you might not have to bypass the cycling switch the get the compressor to run. Then you can get Freon in the system to the point where you can remove the bypass and let the system cycle. If you can get it to cycle somewhat normal, then you can add Freon if necessary to a normal pressure and cycling.
In the end, you may just need a Freon charge.

You really need a set of gauges ($60).

You want to bypass the low pressure switch. It keeps the compressor from running if there is little or no freon in the system.
You unplug the connector on the switch and jumper the two contacts in the connector.
I think I got too close when I took the picture. It loses context:
