Which switch are you messing with ?

There's the CYCLING switch on top of the accumulator, and then there's the
High pressure switch which is in the high side line, towards the front of
the car, by the radiator.

The one you can "jump" to get the compressor going, to install freon, or
just test what's going on is the one with ONLY 2 wires back by the firewall,
on the accum.

You can also go a different route, and use a test lamp to check for 12v on
both sides of the switch. If it is only on one side, then either the switch
is broken, or it is WORKING, and the pressure is too low to engage it.
