2001 E320 RF turn signal problem
 

Helping out a friend here...he has 2 malfunctions on his display - Right front turn signal, check bulb and Back-up light on...right turn signal is blinking really fast - the right side view mirror turn signal light and the right rear signal light are working fine, but the right front bulb is not working at all. Left side works fine...I can not see that the back-up light is on...have no idea what this message is referring to???

The right front turn signal bulb itself is good - switched bulbs with the left side and it works fine. What should I be looking for - any help?

thanks, ryan
