VIN 1FTEW1EP2MKD19779 The dealer is Sunbury Motors, Sunbury, PA. I have had the truck in for this problem and they did replace the multi-function switch (turn signal lever).
I just haven't gotten back to talk to them about it again. This is in no way a complaint about the dealership as they were very quick to work on my problem. It just hasn't corrected it yet.
