Ok, so I am definitely not getting power to the compressor. I swapped out the MAS behind the battery and got no change. I ran a straight hotwire from the positive battery terminal to the clutch and finally got it to engage. What I did was wire up a relay to the compressor so now I have a working a/c again. I obviously still need to find the problem, but I needed something because the temperature here is now in the 110° range and will be this way for the next 3 months ago a/c was imperative. Now that I narrowed it down some I can start looking at the electrical wiring. Any more suggestions are greatly welcomed and appreciated.
