    1981 seville ac compreser wont come on but work when hot wired

    1981 seville ac compreser wont come on but work when hot wired
    I have done eveything asked in manual #S1808 1A-27 trouble tree
    I have all service manuals for this car/year..and the 1981 seville/eldorado electrical troubleshooting manual..
    there is 4volts at the compresser switch circuit 977
    I dont know what and how to check the 3 main parts ,,ECC,,Programer,or the power module to find the problem it would cost $$ to replace these parts only to not be able to fix this compresser not working....
    I think the problem is in 977 circut
    thanks mark
