Rear brake lights out

10

Asked by May 26, 2011 at 09:51 AM about the 2001 Mercedes-Benz M-Class ML 320 4MATIC

Question type: Maintenance & Repair

The brake lights (both of them) on my ML320 are not working.  However, the turn
signals and driving lights are working.  Could this be a blown fuse?  If so, is it easy to
replace?

thank you

Depend in the year of the vehicle the the rear brake lights could be pulse width modulated. A lot of times the vehicle need to be reprogrammed to lower the intensity of the bulbs. This can cause both lights to burn out at the same time. It can also cause the actual light assembly to start to melt. If it is an older vehicle resistors have to be wire in series with lights to prevent them from burning out. I had to do this with my 05 c class for the license plate lamp lights. Otherwise it is very common for bulbs to fail at the same time or close to it. I would first check the bulbs and fuses and go from there. Check for discoloration or deformity in your light assemblies as well. If that is present you know more repair is needed.
