Left rear indicator light/brake light fail

Hi guys.

I searched the forum and found this is a quite common problem.

Yesterday in my dashboard popped up left rear brake light fail, and soon after, left rear indicator light fail (with fast blinking once selected).

The strange things is that if I turn off the car for a while and then start again, I can use turn light and brakes normally but, all at once, fail will pop up again.

Same problem some months ago: my dealer said something about a melt connector but it fixed for less than 10 euros.

Did you guys found any stable solution??

Thanks

As you said, it's a common problem, and the fix has been posted in numerous threads. You need a new connector, again. The only stable fix is to bypass the ground connection through the connector and wire the lamp ground to the chassis ground. This has also been posted numerous times.

Thanks!

Is it an easy DIY? (Any guide?)

It is, there is, you'll find it searching the cosmetic and lighting section.
