I had this anomaly with the cigar lighter and discovered an assembly mistake after some maintenance had been performed in the console area by a previous owner. On the 1973 (maybe other early 107s) the temperature vacuum switch had a 2 pole lead to activate the light in the knob - light came on when the AC compressor activated. An early design change by Mercedes-Benz made this lead obsolete; present but unused. This is documented in the service manual (83.1-542).

In my car, this 2 pole lead had been connected to the side of the ashtray in lieu of the correct 2 pole lead. The only way I found it was by checking the wire colors.
