Just an update for anyone changing fabric seat base only. The TPS part number is 7LA963555C

Hello,

My heated seats are not working. I checked a fuse but everything is fine.
I took it apart and now I see it is not burned out.
A quick check with an ohmmeter shows 20 ohms resistance in the driver's cushion element and 24 ohms in the backrest element.
Can anyone tell me if these are normal values or if they are faulty?

Hi, my drivers seat base element works but on the lowest setting it burns my bum after a few minutes and I have to turn it off. The back rest is not working at all. Any ideas on where to start my investigations??

Passenger works correctly.

@MarksT6
Did you get to the bottom of the fault
I would guess the upper seat pad has short circuit and the seat base pad has all the current from poth pads going in to the lower pad making it get hotter

Yes, you are correct. I checked and the back rest heat pad is faulty but I can't find the correct replacement.
