Seat Heater Testing

[Quattro8880@aol.com]

My seat heater stopped working this morning. The passenger one works, but not 
the driver's side. I removed the connector from under the seat and tried to 
test for voltage.  I followed the wiring diagram in the Bently, but I'm not 
sure of one of the wires. I get 12vdc between the Black w/ Wht stripe and 
brown wires, but I get no voltage from the Black w/ Yellow stripe to any of 
the other pins. Is this correct ? Looking at the diagram, I should get 12vdc 
on the Blk/Yell, shouldn't I.

Is there another way of troubleshooting the seat heater  without taking the 
seat apart. Can it be ohmed out ? Where can I get the specs?
