    also compressor could be nearing end of life. Without gauges and witnessing the readings it’s all speculative on my part

    I got my my Cat C13 reprogrammed from an aftermarket shop. I'm happy with the performance but ever since, the engine fan won't come on for the A/C in slow traffic or when parked. An other shop figured out, the ECM doesn't recognize the A/C and won't turn the fan on. I run it manually when needed.
