Seat heaters don't work left and right. Freezing my nuts off in the morning
The lights in the switches work, high and low position.
If I look at the schematic in the Bentley manual page ELE-246 this would mean that fuses and unloader relay are OK.
I'll have to find the heater elements connectors and check there for continuity.
The problem could be the heater elements (all four then), the wiring, or the switches themselve (both).
Are those heater elements difficult to replace DIY?
