You could wire a light to the monovalve and watch for it's activity. Power out
I think means monovalve open which means heat on.
If the light is always on meaning monovalve closed that would point to a
defective (although good looking) monovalve.
Even if I've got the state backwards (light on versus out) if the monovalve is
always powered to a constant state while having alternating hot and cold it
should point to a bad monovalve.

Yeah, it was cooling just fine. She was driving along the road when
the vents started blowing hot air. The compressor is clicking on and
off while this is happening so I am thinking an electrical glitch.
