Why my left rear light on my mercedes benz 1993 400 sle want turn off

SOURCE: left low beam light doesn't light

Go to autozone and ask them to put it in for you..lol or o'reillys. Youd be surprised at how much they will help you if you ask, It would be hard for me to tell you how, but under your hood on each side of your radiator, you can probably see back of headlight. If not it may have to be removed, just look how it is held in place, If I didn't help you I will if you will provide me more info, I do this for free to help people, please give a me a good rating, I don't have anything to gain by trying to help but for a better rating

Hi there
Its probably not a fuse issue as that would affect both sides.
when you replace a blub especially the brake lights it is possible to deform that nice flat panel of metalic strips and if you look carefully it sometimes breaks the plastic pins on which it sits, this causes poor connection to the functional bulb, the soloution is easy, get a small piece of card and fold it over till its about 2-3 mm thick then wedge it behind the panel of strips (top outside corner for brake light) and hey presto the light should work again, top tip use an umbrella and the electric seat to make sure the brake pedal is deppressed to check if alone.

Barrel fuses used to be made of aluminum and corrode on the copper contacts. Pull fuses and replace. 10-15 dollars now will help get rid of electrical gremlins.

This can not be reset by conventional methods. This must be done through a scan tool. Usually only the dealer scan tool will communicate with the SRS module. If the SRS light is on you have other issues and they must be remedied before the light will go out. There is no way of knowing what the issue is without running codes with the scan tool.

If it wont turn over try the neutral safety switch, if it wont start in neutral either the switch most likely needs to be replaced.
