Birds chirping noise gone, now so is my AC

A while back I would hear the "birds chirping under the good nose" and investigated. I couldn't find any signs of idler or tension pulley failure. They all were spinning and didn't seem abnormal. I haven't heard the noise in a while, but the other weekend I tried running the AC and it only blows ambient temps. I popped the hood and noticed the compressor was not cycling at all. I did some research and saw that for some people it was just a relay issue. So I pulled the AC relay and used a jumper to try to activate the compressor. No cycling, just a faint clicking noise. Does this mean my compressor is shot, or am I not join the circuit correctly? I used the jumper to connect the two relay prong "slots" that are parallel with eachother, not to any of the three slots in front. The jeep runs fine otherwise, but I hate to drive my family or dogs around in the rig on really hot summer says. Any ideas as to what I should try/check next? Thanks

Try checking the refrigerant level with a gauge, a lot of times you simply need to add more for the compressor to start working again.

Will do. That would most likely indicate that I have a leak somewhere, which could be a whole other can o' worms. I'll also check the low pressure switch to see if that is a contributing factor...I'll check back in with an update once I by some refrigerant and check things out.

if it were just an issue of refrigerant level, you'd be able to jump it successfully (which is how you add refrigerant to a system that has leaked to the point of not allowing the compressor to engage)

I've got a gauge if you're in the area and would like to borrow it. I bet that's all it is though. Mine was almost empty in the spring, and made similar noises.
