I have an 1984 380SL and today I noticed that with the light switch off and the ignition switch off the left tail light and the left front parking light will not go off. With the ignition on and the light switch off both lights will go off.
I have cleaned the number #16 fuse terminals and the tail light bulb terminals to no affect. The number 6 hole on the tail light assembly power plug shows 12+ volts with both switches off. The lights will go off when #16 fuse is pulled.
Has anyone encountered this problem or a similar problem and figured out what component failure was the cause?
