i take it that its locked up more than once . it could be that metal matter isn't getting flushed out of system when installing new compressor or its always running high pressures from not enough air flow thru condensor . if compressors lock up in less than a year of each other, it is metal in system
First, look for an air conditioner repair person. Or call Chevrolet Company for advice.
That is a diode. It reduces voltage surges when the compressor kicks off and on.
