Why does my ac compressor clutch keep burning up?

My truck uses a factor denso compressor for an 05 yukon and ever since I got the ac system hooked up and charged it worked great for about 2 days then the compressor clutch stared slipping and smelling bad and blowing dust everywhere. So I took it off and found that it was fucked up pretty bad so I bought a whole brand new clutch with the coil and everything and it worked perfectly for about 2 days also and now its doing the same thing and slipping bad almost to the point where it wont spin. What could cause this to happen on 2 different clutches? Could the system be over charged with freon? Thanks

Did you check/add oil to the system? Sounds like your compressor is seizing up.

Could be the compressor seizing up or the head pressure is too high inside the pump. My money is on the compressor like Hoosier said.

Idk it turns easily and freely and cools excellent as long as the clutch is working right. If it was low on oil wouldnt something inside the compressor fail before it burns up 2 clutches or am I wrong? What would make the pressure too high?

When you turn it are you grabbing the actual pulley or the clutch? Was the system properly vacuumed down and charged? Did you add oil to it when installing it? Also check the voltage going to the clutch. You could not have enough voltage and it might not be engaging all the way.
