I have a 2014 durango and got a right front turn signal out message. We replaced the traditional bulb with an LED bulb and now the front and back light work and are in sync but the mirror turn signal is blinking at double speed. any ideas?

 

It sounds like you did not use a load resistor when you installed the LED lights. The hyperflash is common when switching to LED bulbs if you do not install a load resistor.
