aircon compressor relay chatter

the voltage is low on the relay causing it to chatter. thus the a/c pump does not operate properly. I suspect the compressor control unit.

need help to test my theory
where do I find this CCU

any advice will be appreciated

thank you

Feedback. 6 months later the same problem started again. This time I read that the engine coolant sensor is in series with the relay. I found the wires to the sensor was loss. Soldered every and made sure of good connections. Tested it in 35 degree weather nd it worked like a aircon should.
