I recently decided to retrofit my 2011 with the 2013 tail lights and when I tested them out the passenger side works just fine in sequence but the drivers side one is blinking as a whole unit. I also noticed that it is blinking faster than the right side from the inside. My original tail lights both worked perfect so I know it must be something with that left tail light. Is there a fix or should I pack it up and return it? Any help is greatly appreciated
