A/C clutch voltage issue

[millhouse]

The AC stopped working, this is what appears to the be the root (I have no idea what the cause is).

With the low pressure sensor jumped, I get 12V measured at the AC clutch pigtail ONLY when measured to an actual ground (myself, the chassis etc.). When I try to use the pigtail ground, I get nothing. If I measure the voltage on the pigtail ground, it measures .2-.5v. I checked all relay's and fuses and they appear to be functioning properly (replaced the relay with an adjacent one and noticed the same behavior).

The A/C was working great last year. Now...it's dead.

Any ideas on this matter would be greatly appreciated.

being as no one has replied to your issue, did you ever figure it out? im going through the same issue, but on a 96 and with zero voltage coming from the pigtail

This could be the problem if your still looking.
