Now, if your relay in one seat is bad let me know. I would be interested in it. Maybe I can design something cheap to replace it.

I took the car out for a brief drive and the seat heater was behaving itself - but time will tell. I was expecting a mechanical relay when I opened it up and was surprised to find the following...
