Put some more refrigerant in it and it is still the same. One thing I did notice.....The AC pump was spinning but it didnt seem like it was cycling. After putting some refrigerant in it at least started cycling albeit did sound a bit rough or strained.
Any other ideas or suggestions where to troubleshoot?

If the compressor didn't cycle until you added the refrigerant it is safe to assume the level was really low. By adding the refrigerant it started to cycle meaning that it had enough 134 to start cycling. It would usually be a fast cycle until you reach around 1.75 pounds of refrigerant.
Were you able to add the dye?

I have a 2005 2500HD 4x4 and the blower fan cuts in and out when set on 3 if it cuts out i can tap on the duct n the passenger floor and it will return working. I was told that it was the blower resistor module and I went and bought a new one from autozone it costed around $60 to $65. I was also told it was a comon part to go out so when i took everything apart and got to it i noticed the plug on the end of my harnes that plugs into it was also burned so i taped up the burned wires to prevent it from burning any more and my conections looked good enough to work till i could find another plug so i put everything back together and it worked fine till i hit a bump then back to the way it was. So as for mine I believe the plug needs replaced to fix it and if yours is burned just a little and dont have a firm conection or is loose just a hair i would recomend starting there first its cheeper. As far as finding the plug i havent yet I was gunna try my local junkyards and probably pay $5 or $10 but they dont have anything that new so in waiting for them to get one but for now i keep something to reach and bump the duct when it goes out then its fine till the next bump. I know this Is long and drawn out but I hope it helps you

AC quit blowing on super-high, have been told this could be the recirc gate not closing. How do I test this and other gates, have been told that my truck might have three or four gates with motor actuators. Anybody have a diagram? I'm not very electrically inclined so please keep it simple as possible? Thank you in advance for your help!
