"Turn signal left mirror" Problem in C320 ( 2005 )
Hi, everyone, About my C320 ( 2005 ), the Left turning signal light in the left mirror cannot light up today. and the turning sound ( tick tick ) become faster than usual, My heart got nervous so much when the sound becoming faster. please see the following picture:
how may I fix this issue by myself? any suggestion, please?
The annoying part is: The "tick tick tick" turning sound as fast as a bomb in the final few seconds.
(The weird thing is: this issue recovered just for few seconds when I did something that I really don't know what I have done, I just open the hood and clear somewhere, and close the hood a little harder, then when I just plug the key in, try the left signal, the problem is gone, but when I turn on the engine and make a left turn, the problem comes back again )
Thank you, everyone!
Now this light does work anymore, and the turning sound as fast as a bomb in its final seconds, this makes me very nervous!
Update at 29/3/2018 :
I opened the mirror case by watching the Youtube Video:
And I might found something inside, maybe it caused by water:
After cleaning the Green Color part and let the sunshine dried it, it has been fixed perfectly!
Hope this post could help someone who has the same problem.
Common issue, had this happen today. The bulbs are LED, sometimes the mirror housing just needs to be seated properly...usually goes away by itself. No need to hyperventilate

Thank you RWDlifer & mbdr: but the faster turning sound makes me very flustered and nervous ~~
I've been dealing with this problem pretty much since I got my car. It used to be intermittent and random, and seemingly would go away during the winter. Lately it's been back full time and so I took apart my mirrors. Sure enough, somehow each turn signal's connection corroded so badly that exactly 1 pin has broken off into the socket. I contacted my local stealer and can get the replacement turn signals for a (surprisingly) reasonable price, but I'm not sure how to approach fixing the sockets. The driver side one is entirely missing a pin, and the passenger side one is missing 3/4 of one pin. Any ideas?

This is absolutely the BEST kind of thread. Problem identified,
OP uses the forum to find solution, posts pics of the resolution, and closes out the thread
letting everyone know the end result.
Kudos!!!
So many threads just end and no one knows the result. You da man!

If you are lucky there may be a repair kit.
The pn's are hard to find, but often do exist.
Example, MB sells the connectors for the side markers,
Mine was damaged and I bought a couple extra which has come in handy over the years,
as people seem to smash into them.
It might take some searching a very competant parts person at a dealer, but you might get lucky!

I ended up band-aiding my problem by tricking the car into thinking the turn signals are connected using a 100ohm resistor between the male pins and leaving the turn signals disconnected. They're not really necessary, and currently not worth the $100 for me. So far it's been a few days and everything is fine. If things continue to be fine for another month I'll take apart my handywork and look for any signs of overheating on the resistors. Here's hoping.
Jumping on to this thread in hopes of finding a solution...
New-to-us car in January.
Same message/issue came up for us with intermittent function/problems including the fast-ticking.
Car is with my son at College, so I simply planned on addressing it this past week when he was home. The issue was intermittent enough that we weren't sure we'd need to replace anything...
Well, ordered new light/units for both sides. Took it apart yesterday and still can't get the problematic side to work (note: previously functioning side works with new lights, too).
Interesting to note that the speedy ticking is NOT consistent.
Both pins seemed okay. Also tried using some dielectric grease in putting it back together and wiggled all the wires (behind the mirror as well as from body to door) in hopes that I might be able to find a bad section.
VTMike,
I think I would put a multimeter on the socket in the mirror base to see if current is making it that far. You might need to tweak the connectors in the mirror base to ensure a good path for current when the mirror housing is re-installed. If there is no current at the mirror base, then you are likely looking for a bad wire somewhere in the door or the harness. Good luck.

I tried the multimeter and had current to the two prongs. My hunch is that it wasn't seating correctly.
I took it apart, inspected everything, and then buttoned it back up for the drive back to College. Hopefully it will heal itself :-). If not, it will be part of my to-do list when he gets back.
(though I would appreciate any other suggestions or tips)
From my experience with this issue, the fast-clicking was being caused by the mirror being effectively disconnected and not drawing enough current/high enough voltage from the door controls module. Any time that I wasn't getting fast clicking, the turn signals were actually working regardless of any dashboard messages. So if you're getting fast clicking intermittently, it might be an intermittent break in the connection between the turn signals and the controls module in the door (the one linked to the power locks, power windows, power mirrors). If it's not exactly at the connection point in the mirror, it could be somewhere else down the line. You'll need to take the door apart.
I tried to clean up the two connections I could easily access. I didn't pull the wire-harness that was there ~ I wasn't sure I could do so without separating the mirror and I didn't want to tackle that.
On the positive side, it worked for his ride home ~~ so here's hoping.
Back to trying to tackle this issue as I think I'm getting some excess current draw from it, too.
Replaced both sides with FER units from RMEuropean. Passenger side unit worked perfectly from the start, driver's side was intermittent. Typically would work when initially turned on, then it would race to faster tick-tick-tick.
Took the unit apart and tried deforming the pins a little by squeezing with needle nose pliers. Thought/hope was that I'd increase contact in the female side. Minor improvement, but still temperamental.
Passenger side has now stopped working.
Just tried putting original units back in, cleaning everything up really well, and neither side is working.
In hindsight, I should have tried plugging the units in without the mirror to see if it seems to be a connection issue or a wiring issue.
Can do that later/another day.
Suggestions?
Odd that both sides are fatiguing/presenting problems?
Opened it back up tonight and connected JUST the lights without the mirror cowling. That worked. That made me more certain that it was the connection.
Considered clipping the two plastic tabs off of the pin-harness, but decided against that. Instead, took a wire-tie and clipped the end and put that behind it to put a little bit of tension on the prong-side of the connection. I didn't want something to impinge on the wires or something that would be prone to weather issues. I didn't glue it in, but it seems to do the trick at this point. I'll update in a few months with hopes that it continues to work well.

"Turn signal left mirror" Problem in C320 ( 2005 )
, I will buy a new LED light part and try to replace it by myself. I hope this issue is not caused by some wire line! 
You da man!
