Has anyone ever had a fried, or messed up multi-function switch? What were the symptoms?

 

Wipers would turn on on there own and the blinker would stay on in the dash but not outside of the truck

 

Easy to change.

Most of the time its not the multi function switch bad. Its usually the pigtail wiring that goes to the multifunction switch, expecially if it has tilt steering. Original wiring harnesses were too short. And when you tilted the wheel all the way down, It will pull the wires out of the plug.

 

Yeah, my right turn signal and brake light would not work as soon as you drove forward, it had a bad connection. Dealer replaced it, now it's all good!
