95 E320 Wagon Turn light woes

[cleavster]

Hi Folks,

The bulb warning light came on today as I was making a left hand turn. The rear driver side was not working and the front driver side signal was flashing very fast. I changed the rear bulb with a known good one and still does not work when engaged by the turn signal switch or the hazard switch. All lights are working for both the front and the back except for the rear driver side turn signal. I tested the rear driver side bulb holder to the passenger side and everything works. So, I know its not the bulb holder or the bulbs.

I checked the fuses and nothing is burned out. Is there a specific fuse or relay that I need to change or test? I'm stumped right now. Thanks in advance.

Cheers.
