Hello. I have a 2006 ML350 ....I experienced the fast flashing when signaling for left turns (the rear). The display message showed "change rear bulb"...
I changed it but started to get the same message with the fast flashing again...
The bulb was good and after i checked it, everything was fine for a day but the fast flashing and message reappeared again. Sometimes the fast flashing messages says; the right side but the bulbs are fine....I was thinking it could be a fuse or relay. Help...Help...Help..:. If it is the relay, where would i find it?

thanks again

 

Hello and welcome to the forum. I'm attaching a link to the relay locations to troubleshoot your issue. It does sound like it's a faulty or loose fuse. Please let us know if you have any other questions or if we can help you with any part needs.
