This is a Big Job but Easy when you know How.

The main Problem is a Bad Connector to the Seat Heating Control Module

so the First Thing To Do is to Remove the Seat from the car.

.......... Stage one ....... SEAT REMOVAL ......... 

Disconnect the Main Connector from under the Seat 

then Remove the Two T50 Bolts from the Rails at the back of the Seat

Push the Seat up and Pull it Back to get the Seat out from the Car

then Turn the Seat on its Side and Remove the Plastic Cover 

For the Seat Belt Presenter use a T50 Socket and Remove the Bolt 

Then Under the Seat Unclip the Yellow Connector and take the Seat out. 

........... Stage two ............. REPLACE THE CONNECTOR ON THE MODULE .............

Disconnect the Center Connector on the Seat Heating Control Module

Strip the Loom Tape Back and Cut the old Connector from the Loom Make a Note of what Color Wires

Go too in each Position on the Connector add the New Pins to the New Connector in the Correct Positions 

Then Join the Wires back Together making Sure you have some Slack on the Cable and Re Wrap with Loom Tape and Reconnect.

This is the First Thing to Try as This is the Course of the Fault
