A/C Compressor Won't Kick On

We fixed the vacuum problem, just as stated in a preceeding post........dash works a-ok now..........BUT, the compressor did not cycle at all in a/c mode.

I hot wired the compressor, and it worked fine.......I cycled it a bit, then hooked up a 134a can and gauge...........after discovering an inlet valve problem and fixing it, I did it again...........cycled through a half can...........just a half can.........and the pressure read at the max of the blue zone (safe zone)............If I put in any more, it will go into the yellow and red...............there is not enough coolant in there to really do much good.........I could feel a "wee bit" now and then during the test.

OK................we have not enough coolant in the system, and too much pressure if we try to put in more...........

What now?......................Any A/C men out there???

By the way, if we hook the pressure switch back up the way it was, the compressor still will not cycle on it's own............does this switch activate the cycling?...............or is it something else?
