No heated seat on drivers side. I’ve done some measurements and found that there are different ohn readings of the thermistor (yellow leads) between driver and passenger side. 4.6 kOhm on the non functional side and 9.6 kOhm on functional side. Is that the provlem and causes the module to shot down the power to the heating pads? Or can it still be the module?

Would a heater module interchange help with isolating the cause?

That’s a good idea. I was just curious to know if the difference in resistence could make the heater to stop working completely.
