I Have A 85 Cutlass Supreme. I Had The Ac Recharged And When I Turn The Ac On, The Compressor Clicks On For A Second TheN Clicks Again And It Keeps On Doing That. I HeaRd That I Might Have Something Stuck In One Of The Lines, But I Cleared Out The Orfis?? Tube. And It Still DOES THE SAME THING . Is There Anything Else I Can Do Or What I Should Do To Fix It. Thanks

It sounds like the AC recharge has leaked out. The shrader valve may have a leak in it. The constant cycling indicates that the AC is low on refrigerant and is constantly cycling.

I agree with "Pops", you have to fix your leak.
What is your low side pressure? Did you pull a vacuum after cleaning your orifice tube? Air and refrigerant don't work together, the air doesn't compress back to a liquid in a car system like a refrigerant and the pressure will build until you start setting off the high pressure cutoff switch and the compressor will cycle.
NOW for the legalities...you have to have the system properly evacuated by a certified AC repair facility before making any repairs to be sure no refrigerant gasses escape into the atmosphere and the gasses not reintroduced until repairs are made.
