Caravan (or any) A/C clutch diagnostics

.... (Hey guys do you have a little brother that complains and complains and when he finally brings you his car to find out what's up he brings it over while it's raining?? Mine did)
No, I got a 21 year old that refuses to roll down his window after I fixed the 3rd guide pin that had come out, causing the window to **** and bind. BTW he has no AC either so he's gonna be sweating unless he trusts me on that window now.

So I got a pigtail for that clutch harness at the junk yard and will test 12V in to see if this thing clicks. I hope it doesn't as that is a cheap fix. If it does cycle I'm F'd. R134 in California is like gold gas, priced the same.
