front heated seats
 

The front heated seats on my 89 300sel are not functioning. The fuses are good and when the button is pressed the LED lights in both modes. Both the front seats are not heating. Any tips for diagnosis is appreciated.

Anybody with clues where to start looking.

Upon looking at the electrical diagrams of my car 300sel 89. It says AS OF MY89 there is a fuse in the auxillary holder (F22/1). This is not part of the fuse box. Just cant locate this fuse and it is not mentioned in the electrical diagrams book. Anybody with a MY 89 and later who has the electrcal book point me to the location of the fuse. Appreciated

Get a meter across the terminals, and measure for voltage. If you don't find any, trace your way back through the circuit until you do.
