How does it manage to work for a while if it is blocked? Or is it just
partly blocked? Does that cause the pressure to rise too high?
Is there no pressure sensor to tell the unit to shut down before it
damages itself?

Pressure goes super high, then the compressor fails. It will cool for about
30-40 minutes per compressor. Has new evaporator, new expansion valve new
drier, now on compressor #3 (or about to be). Control unit is new. At least
one new pressure hose. All the vac pods are new, as is the dash. Works
great for awhile, then gradually gets warmer over an hour or so, and that's
it.
Any ideas on how to troubleshoot this further? Tired of throwing
compressors at it. Nippodenso units from rock auto, same as original. Of
course the motor is a 606 now.
Thanks
