I have a 2012 F250. The signal lights just quit blinking when you hit the lever. If you hold it in the signal position it blinks regularly. This duty is the model where the signal arm returns back to center after you actuate it. Anybody else have this issue?

 

May be the stalk itself. I had an issue in my 2011 with my wipers going on by themselves and the ww fluid not always working ; replaced the multifunction stalk and everything was good.
