2007 MINI Cooper S with cloth heated seats …

I love the 3-level "warm - hot - buns on fire" selections of the MINI heated seats, particularly on my high-mileage aching back. Not so much on the buns. Has anyone found a way to turn off or unplug the heated seat bottom but still have the heated seat back? Anyone have access to the seat wiring diagram? The preferred option would be a simple unplug so I don't have to permanently change the wiring for future owners.

 

Dig through newtis.info for wiring. You might have to add a resistor to keep the circuit functional.

 

The Bentley manual show connector X732 feeds 2 wires to the seat backrest heating (passenger is X0732),
and X733 feeds 3 wires to the driver's seat cushion (terminal 3 goes to the thermistor that regulates the heat,
terminal 4 goes to the heating resistor, and terminal 1 grounds both) (passenger is X0733).

So if you unplug the seat bottom, the system is no longer temperature regulated and won't work properly; it might not work at all.
Page 520-3 has a simpler schematic than in the wiring diagrams and page 520-4 has the locations of the connectors under the seats.

Here's an image of part of the wiring diagram (ELE-189 - ELE-192):

 

 

All three heat settings feel the same to me, it's been like that since it was new.

 

Same here.

 

Yes, i think it just pulsates the heat more on/off with each level .
