I replaced the A/c compressor on the Mrs. Accord made sure refrigerant was full but the compressor just isn't engaging. I know I'm not getting a ground signal from the PCM. I've replaced the thermal switch, the switch on the dash, I've even replaced the blower motor resistor due to a video I watched staying it was tied into the system. This car has me stumped. Anyone have any insight on possible causes and repairs? Any info would be great. Thanks in advance.
