My AC stopped working last summer but I never got around to fixing it. I now am troubleshooting it and noticed that if I try to bypass the AC relay by supplying 12 volts to the AC clutch from the fuse box, middle P/Y terminal of relay, the clutch does not engage. That would mean a broken wire somewhere as the current can't get to the clutch? Does anyone know where that wiring harness is routed? I will try 12 volts straight at the AC compressor to see if it engages the clutch.
