Good day all,
I have a 2014 MS. My cabin heater stopped working this November and, after some research, found out the PTC module often short-circuit the fuses in the DC-DC converter. I ordered a Gen 3 PTC and installed it. The position is the same in the car, the connector also fits despite being quite shorter than the older version. After restarting the car, I now have an error message. I didn't change the fuses as the DC-DC converter I saw in the videos and posts is not the same as mine (mine is located behind the frunk plastic trim as opposed to behind the passenger wheel).
Do you know if there is an extra module in the Gen 3 PTC that tells the MCU when its not receiving current to work?
