My service manual says nothing about them, The passenger seat works fine but the driver side does not. There is power to the switch and the rocker switch stays "brite" for a few seconds when pushed but then shuts itself back to idle mode..Seat won't heat up...Any idea's........

I had the same problem. In my case removing the switch(es), taking them apart and cleaning the contacts solved the problem completely. You have to be careful as the relay board for the seat heater is part of the switch assembly. Because of their location a lot of dirt and spilled liquids finds their way inside the switch. I found coffee residue in mine and once I had cleaned them up with electrical contact cleaner, they worked fine in both low and high settings.
