Normal Operation

WARNING: This page is about a different car, the 2005 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.

The instrument cluster sends out a voltage reference signal through circuit 8-LG43 (WH/VT) to the multifunction switch. The return signal is carried through circuit 9-LG43 (BN/WH) (shared with the high beam circuit) back to the instrument cluster. When the multifunction switch is placed in the RH or LH turn positions, the voltage signal sent by the instrument cluster passes through a resistor within the multifunction switch (specific to LH and RH turn positions) before returning to instrument cluster.
