Thought my a/c was fixed but is not. This is the problem: no cold air, even though clutch cycles on. Checked low side pressure and it was at 80psi with car off. Brought it down to about 45psi with car off. Once I turn on the car and a/c I get 0. No pressure at all on the outside though the clutch still cycles on when I turn a/c on.
