I drive a 2010 w169, Mercedes A-Class a180 cdi
and I started to notice that my left LED turn indicator in the mirror on the driver’s side blinks too fast at times, flashing rapidly.
It happens very irregularly. I noticed it first when I locked my car in a parking lot in the dark,
when I saw that, I tried using the left turning signal and those LEDs in the mirror continued to flash rapidly.
Inside the car I never heard a noise or clicking noises so far. My indicator lights in the dashboard also seem to work fine.
Most of the time it doesn’t happen and all turn signals work as they should.
At first I thought a bulb needed replacement, but they are all intact.
Since I’m not knowledgeable about cars, I google’d some info and looked at my grounding wires, they look a little corroded, but are not loose. (it were 3 or 4 brown cables coming together at the same point on the right front side under the hood)
I tried looking at the bulb connectors, but they’re all in a “sealed” compartment and pretty hard to get a good look at in the w169. So didn’t really check the connectors, but all lights work without a problem.
I might take out the left and right indicator lights next to the headlights, as those seem not hard to do.
I looked at my fuse box, but really, I just looked, I know nothing about electronics (or cars for that matter), so I just made sure nothing was loose.
Nothing seemed to be broken or burnt through at first glance.
I tried my blinkers a ton of times and most of the time they work as normal.
so I’m really confused as to why the driver’s side mirror LEDs speed up sometime. There must be a reason.
Is there a bulb on it’s way out? I took out and checked all the bulbs in the rear, all good there.
I wanted to go to a garage, but I’m probably gonna show up and it will all be working fine (that’s how it usually goes)
I haven’t yet found a pattern when it’s most likely to happen, but I’ll keep an eye on it
When it’s sitting in my garage and I test it, it seems to not happen; after driving it a while and when I park my car and lock is usually when I notice it.
The only other thing I ever noticed is that one of the lights in my interior lighting above my head is not working, not sure if that can have anything to do with it?
Has anybody ever have this experience?
I’m curious to see if anyone has had a similar experience and how you fixed it,
thanks in advance!
