AC compressor clutch not getting power

[Ben Swann]

Tony,

I was wondering how to do this, as they seem to be hard wired.  Where are the connectors for these?

  Check the low and high switches. Unplug and short them one at a time.

    pressure side during operation and outside temp around 80 deg. F. Climate
    control set to low and everything operates except for compressor clutch is
    not engaging. Applying power directly to compressor engages clutch and
    system blows nice and cold.

    I noticed on the one I was just working on that there was no relay in
    position number 6 where the fuse box cover indicates AC relay should be.
    Inserting relay makes no difference.

    Any clues as to what is going on? BTDT on common culprit(s)?
