Get some guages and check the pressure in the system.
While AC is on, low side should be between 40 - 45 psi
High side will be between 200 - 250 psi.
If you just stick guages on w/ AC off, then pressure should be even between both sides.
Maybe 50 - 65 psi both High and low.

Another quick way to tell is if you turn on the A/C and the clutch doesn't kick in.
Usually means no pressure....so an empty or low system.
On my 91 Chevy, it will cause the A/C display on my panel to blink.
