Dear all,

I have retrofitted manual sport seats on my 2006 E91. So far, all bolsters work but the seat heating doesn't.
We have checked the wiring multiple times, coded multiple times, and the lights on the dashboard work correctly (no blinking or anything), but the seats don't heat up. I have read that there are some junction boxes that don't support seat heating, so this might be my issue. Can someone tell me which models of junction boxes exist and which of those would be sure to work with heated seats? Thanks a lot in advance!
