The right mirror turn signal on my C230K is no longer working.I'm also getting a message informing me of the problem. How much is involved fixing this and what is the estimated cost?
Thanks.

 

Mine did the same thing. After approx one two weeks is began working again. It has since done it once more, but only took a few days to work again. If you use a high pressure car wash, you might check to see if there is condensation in the light. I noticed that it occurred the last time after I used the wash and once the condensation cleared, that's when it started working again. I had looked, and found, a light on EBAY for $45.

 

Now it's working again. After sitting for about 8 hours I go out and the blinker is working and no error message on my screen. Finish visiting a friend, start the car and the blinker is still working but the error message is back. Pull into my drive way turn the car off, then on again, the message is gone. This happened for a couple week last October. I don't get it.
