Does anyone know how exactly the Heated Seat circuit works?

My heated seat only seems to work occasionally.

The switch works fine, and the indicator lights work (HI & LOW) as well.


Is there anything special that needs to occur for the seat heaters to work?

I.E.:

Car in motion
Car in Drive
Downward pressure on seat (seated person).

Hopefully I am not the first person to have this problem.

Thanks,
