My 2014 250 SHO will not go down intermittently for the last year. It works most of the time, but when it stops it will not work for the entire day until I get it home and put away. As soon as I try it in the garage it's working again. It only quits at the shifter and the blinker trim at the steering wheel. It always works at the switch on the motor and it is always down that quits. Up always works. Has anyone else ever had this symptom and figured it out. I have looked at the wiring and everything seems to be fine. Help Please!
