Thanks for the reply. The ports are completely dry, that is for sure. I checked the wiring harness for continuity using a multimeter and the wiring harness is good. The wiring harness from AC compressor ends in the fuse box, which is where i performed the test.

What should my next step be? Which connections are you mentioning ? Where is the ECU and AC amplifier.

I really appreciate anyone helping me out on this. Thank you.

Hello. My 3rd Prius A/c pump is not working. I replaced the pump and it is the same. The high voltage fuse and the small black connector port inside the inverter are clean. What should I check now?
