04 L322 - The rear switch for the seat heater is not working - when I push it in the light comes on but then goes out as soon as you remove your finger - closer inspection has revealed that the switch is actually broken around the tiny light sections - I want to try swapping the switches over to make sure that the switch is why the seat is not working but I cannot find any information about removing said switch. The panel has 2 seat switches and an Aux power outlet.

Go on to the powerfuluk website look in interior trim you will find the rear switch panel then scroll down there is a video of how to remove it
