compressor clutch problem
The compressor plug has no juice. Does anyone know where the harness feeds from. Would I be looking in the dash? I have power from the fuse box, but not to the plug to the compressor.

There are high and low pressure switches that protect the system, if you're low on coolant the low pressure switch will keep the compressor from going on to protect it from low oil damage. To charge the system, you would have to jump out the low pressure switch to kick-on the compressor while you start charging the system. I'll bet you're low on freon and the low pressure switch has bypassed the compressor. The oil lubracates the system and the low pressure switch is a "fail-safe" to insure that no bearing damage occures to the pump. The high pressure switch kills the compressor when there is too much pressure, which can blow seals ect. What I would do is bring power right to the compressor and if it kicks on, you know it's an in-line switch. There should also be a relay, you might want to check that out as well.
