SEL126

Hey guys, about to purchase a 2012 CL550, the driver’s side front turn signal doesn’t illuminate. The white LEDs work but when the turn/hazzards are put on it goes dead instead of switching to amber. I haven’t been able to find any info posted so I’m guessing it’s not a common issue. Trying to figure out if it would be an led issue, or maybe a driver for the switchbacks? Would the whole headlight assembly have to be changed? Obviously I want as much info as possible in order to base my offer when buying the car. Any & all help is greatly appreciated!
Thanks,
Scott
