94 sable/ No power at compressor

Hi All, I have a 1994 mercury sable with 3.0 liter eng. I replaced compressor cause it took a dump. Ran a vacume on sys for 40 minutes. When I started to put freon in the compressor was not comming on so I jumped the low pressure cut-out switch and still nothing. I checked wires at compressor and I have no power at all. I checked all fuses and all is fine. Is there a clutch relay or something that I might have missed Any Help would be Greatly Appreciated. Thank You In Advance

Just to give everyone an up-date. Upon further testing it turned out to be a bad Body Control Module Cost around $100.00 bucks. So if anyone is having the same type of problem as me that gives you something to check. Thank you:grinyes::grinyes:
