2010 volvo xc60 ac issues

[Ju015dd]

Ac not working, I don't really know much about these vehicles and will try to list all I have done so far and have observed. With car running and ac on compressor acts like it is trying to engage but is not. I have verified power to the clutch and pulled relay just to see if power would come and go to compressor plug. There are two different plugs on my compressor. One closer to the clutch itself which if I unplug it the compressor wheel looks to freely spin. The other plug which is on the far side of the compressor (closer to drivers side of car) while unplugged lets compressor wheel spin freely then once plugged back it after 30 - 60 sec will start acting like it is engaging then stop. I have noticed it compressor makes a faint clicking sound when clutch is what I would call stuttering.

Also, I went and bought one of the ac kits to try and add some refrigerant with no luck. As soon as I hook it up to the low side port gauge will more than max out and will not let me add anything. Wasn't sure if this was due to compressor not coming on or bad gauge on this cheap can of ac fix it, or I have some serious pressure on the low side line.

Any thing would help guys, thanks!!
