Not yet. The turn signal switch at the steering column is broken. I have to hold it down when signaling left. I've ordered the replacement part from Freightliner.
On a two-filament system the brake filament and and the turn signal filament are one and the same, so this is perplexing. Could the power to the left brake light route through the turn signal switch? Without a schematic I can't tell. Bottom line is: The turn signal switch has to be replaced no matter what. In a perfect world the brake light problem will be fixed. In my world... Probably not!
As I learn more I'll certainly share with the forum.
