Anyone know which plugs are which for heated seat

[Portisz4]

I need to know which plug is which for the heated seat connections.
Any clever soul know ? I have lost the heating on the bottom part of the driver seat but the sides and back work.
I've swapped the control modules And they both work on the passenger seat.

Ah ok. And I have ista running here at the moment. Is it able to tell me anything about the heated seats ???

Bit weird really. Doesn't show any issues but the bottom of the seat doesn't heat.

It's it easy to take the leather off to see the heating wires?

I’m not an ISTA fan so not sure if it would or wouldn’t diagnose a faulty seat heater..

I suspect taking a seat apart to troubleshoot it would be a one way street for many..

Well, I found an old seat bottom at a scrappy. Plugged it in and it works so somewhere inside mine it's come disconnected or a broken wire somehow. Strange how the side thigh bits still get hot though

What to do

Take seat apart.
