- 2001 E240 Elegance Wagon (S210)
Hello! I have a 2001 MB E240 Elegance Wagon S210
Problem: My right side brake light fails but works for a period of time when the bulb carrier is reseated.
Is there a fickle thing with these I'm not seeing? Is there some kind of power short protection - that is not a fusible link - that is failing and can be reset by reseating the bulb carrier? What would be the point of fuses if you can cut power to a single bulb?
Background: I have this odd problem. I had a brake light out but only on the right side - So I changed it. It failed again - so I changed it. It failed a third time - so I swapped sides completely with the bulbs and bulbs carriers, They both worked! Then the right one failed in a day. I simply reseated the bulb carrier and it worked for three days. Then it failed again. Each time I get a bulb out error on the cluster.
My logical path:
- Its not the bulb carrier because I swapped them
- Its not corrosion because I pulled all of the bulb carriers and scraped the contacts clean.
- Its not blown fuses, though I checked, because I'd be replacing them over and over and not reseating this one bulb
- I don't think its a relay? Can they fail like this?
- It doesn't seem to be bare wiring because sometimes it fails in the driveway and sometimes it goes for days and days without failing
- Its not the bulbs or a loose filament. I replaced the bulbs and swapped sides.
Thank you in advance for your time!
