Well, this is odd and hopefully someone out here can help me.
As title says, my A/C compressor is cycling too fast; 3-4 seconds on and then 2-3 seconds off, then over and over again.
Please take a look at this video; THIS IS MY TRUCK RUNNING:

Low on R-134a? Maybe, but the air conditioner blows ice cold inside the cab.
Please note the following:
1- Ive disconnected and jumped the low pressure switch: the compressor runs constantly blowing ice cold inside the cab.
2- There are absolutely no leacks on the a/c system. NONE
3- Whenever the a/c clutch engages/disengages, I can hear a "click" comming from the fuse-relay box inside the engine compartment. Im not sure if its the WOT relay (maybe), but when the compressor turns on, I can clearly hear a relay clicking.
4- The a/c clutch engages and dissengages perfectly. No strage sounds, no spinning when dissengaged, nothing.
So, as far as I know, this could be:
a- low R-134a refrigerant
b- bad low pressure switch (Ive ordered a new one from Rockauto just in case).
c- both a and b.
Can somebody help me?
Any input, test I should do, anything!
Thanks a lot for your time!
