Fast cycling a/c compressor

[Markus Escamilla]

So my refrigerant leaked out of my compressor (it was hissing out if the compressor) i used r134a with dye and the ac gauge showed full but the compressor kept fast cycling and no cold air even came out...it takes abt a day to leak out completely. I thought that i might have had a bad clutch switch so i changed that and filled the ac system with r134a with dye and it still fast cycled and i still couldn't see an uv dye coming from the hissing compressor

are you using a black light , i you have dye it and its  leaking it will show up , try a spray bottle and soapy water, bubbles will show the leaks, just spray each connection one at a time till you see bubbles forming
