    A/C idle bump not working

    Just as the title says, the idle bump is not working whenever I turn on the AC compressor. Car has been like this since I purchased it as an M50 swap car. Was curious if any of you could shine a light as to how I would begin diagnostic? Thank you-

    Have you wired it in correctly?

      P.O. wired it in, not me, hence my post. Just looking for guidance on diagnosing and determining if wiring is correct, etc. Thanks-

        Start at post 47. Most miss the necessary relay. I still need to do this on mine.
