Part 2: Did I MIS-DIAGNOSE This Mercedes?? (GL450 no A/C - Crazy REPAIR!)
The owner brought his 2012 Mercedes Benz GL450 to my shop along with the original A/C compressor and junkyard replacement HVAC module. Let's get out the big guns (PicoScope!), and take a DEEP DIVE to see why the HVAC controller is NOT HAPPY with the A/C compressor, throwing a SHORT CIRCUIT code on the control wire. Can we get this A/C system to function PROPERLY with the parts on hand?? IVAN'S PICO WAVEFORMS: https://drive.google.com/drive/folder...
