Slightly different Seat Heater Question

[Bryan Kamerer <bk@ibm.net>]

        While I have followed the routine seat heater questions, my problem
is slightly different - the driver's seat gets burning hot in one spot
(under driver's left thigh near front of seat - seems to be right at
junction between seat bottom and left thigh bolster).  Seems to do this
regardless of heat setting - broken/loose connection here or a worn-through
wire or element?  Any ideas?

        If important, seats are Recaros-style leather in a V8.
