My 88 e had the same light go on....checked out all the tail lights, front lights, everything ok....it was the 3rd brake light in the rear window that was out...my glass is limo tinted, so it was very difficult to know it was malfunctioning.
Refrain from having your foot on the brake pedal during the first part of this short test.
When you first turn on the ign. all the warning lamps will light as a 'bulb check' before the engine is started. As soon as the engine starts they all go out. Leave engine running & trans. in P, for now.
If a park lamp or taillight is out, as soon as you turn on the parking lamps that warning lamp will come on and stay on while the circuit is energized. A walk around the car will tell you which is out.
If the bulb remains unlit (engine running), then comes on when the headlights are turned on..... headlamp bulb.
OK so far? With the engine running, put your foot on the brake. If the warning lamp comes on there you go, it is one of them. Also, the thing about the bulb failure light & brake lights is different than the other circuits. If a brake lamp bulb has failed the lamp REMAINS LIT, even with your foot OFF the brake pedal.
When you shut off the ignition the bulb failure circuit resets itself.
So, if that bulb light stays on during the day (no lights on), one of the brake lights is out. Been there with my 126.
wow,thanks very much. very informative. i will try this right when i get out of school today.... reminds me.. i gotta get a parking permit.... well thanks. hopefully its just the brake light that went out... thats what i think it is...
hmm ok, well the right brake light was out and i went to go replace the left so it would be an even replacement . and when i get there..the brake bulb is loose like where it goes in.. in its socket.. so i put a new one in and it doesn't lock in place.... it stays loose and moves around. it made contact a while but then i checked to see if it stuck and it was still loose. i checked the brake by the help of my mom and light ddn't turn on... ideas????
Take the whole bulb assembly piece out of the car!There is a plug you have to unplug at the bottom of the bulb tray! When you have this out, you can carefully take apart the metal bracket and slowly bend all the contacts upwards a little(try not to break the plastic piece)...If done carefully, your bulbs will stay snug in place!!
I just purchased this vehicle and it idles a little rough so I removed the air cleaner to check the vacuum lines and I found one that does not have a place that I can see to connect, I am not sure what it is and if I can just block it off. I haver attached a photo.
Hi guys, just picked up an earlier 2009 c200 Kompressor with only 46k on it.. The merc dealers assured me its normal for super charged models to be noisey on cold starts.. Sort of a mild whining noise for about a minute or so.. Does anyone else experience that maybe from new? The other thing I’d...
I'm a total newbie to the M-B world, and I pick up my new-to-me 2018 SLC 300 on Monday. So, I've been scouring the internet for the best sources of information on the car. Unfortunately, I'm not finding much on this particular model.
I realize this has never been a high volume car...
Lately, when I tap on signal to change lane (right), it blinks 3 times as normal. Then, roughly half the time, left signal immediately blink 3 times as I tapped on it! I searched this and other forums and no luck finding similar discussion. Is this switch related or likely an electrical problem...
