Exactly. AFAIK, there's a "window" switch, which doesn't allow the
compressor to start if there is too low OR too high gas pressure in the
system, so it just works when the pressure is within the "window's" range.

Thanks, I checked that, the contacts are closed, there's another set of
contacts which activates higher fan speed when the pressure gets highish.
Shorted all (with a low value resistor to avoid any inadvertant damage) but
nothing made the compressor clutch click in.
