Buzzer going on with lights.

Hi, I drive a 1995 200e w124. The electrics are playing up a bit, but one problem I am really stumped with is when I turn the lights on a buzzer goes off. Its the same warning buzzer, that goes off, if you had lights on and open the door to get out.
How can I solve this problem or if not solve how can I disconnect/disable the buzzer.

Thanks

Hi B1dft - welcome to the forum.

It sounds like you've got an earth problem or perhaps some leaks? Are your carpets in the foot wells wet?

Hi Army, thanks for the welcome. No the foot wells are perfectly dry, so it could be an earth problem. Could you suggest how I check it out.

Thinking about it Army, there is a fog bulb gone in the back. It often gets wet there (in the boot, by the light casein) as I am often transporting buckets of water (I am a part time window cleaner) and sometimes they splash ect. Also i am having lots of trouble closing my boot, I need to slam it down a couple of times before it closes. (My central locking is not working, so i just put it down to that, another job on my list) Could the slamming have moved the earth, or the splashing of water, damaged the earth, even thought the other lights are all working.
Thanks for the help.

I'm no expert on your car - if you don't have wiring diagrams a bit of a search in google ("W124 wiring diagram") came up with a thread on this forum

W124 wiring diagrams

There were also the following hits on BenzWorld

http://www.benzworld.org/forums/w124-e-ce-d-td-class/1336430-w124-230e-1988-c-wiring-diagram.html

And MBclubuk

They might have the right one for you. Who knows the rear fog light might be on the same fuse as the buzzer - it kind of makes sense... but I don't know for sure - hence the multi links to diagrams...

This could be a red herring though.

The first thing I would do is check under the dash for anything obvious => meaning find where the earth points are and see if they are corroded. And if you let the buzzer buzz you might even find it this way - who knows!

As for your boot not closing properly (most people here call it a trunk by the way!) look at lubricating the mechanism and check the condition of the rubbers. You might find it works a bit better after a clean and lube. Otherwise you will probably find there is a little bit of adjustment on the catch. Does your car have a boot release lever by the driver's seat? If so clean and lubricate that end too.

Army, they are great links and thank you for taking the time in getting and posting them.

The buzzer problem, is kind of pointing, to the switch on the door, it seems to be sending the wrong signal, that the door is open and the lights are on.

On the boot (trunk) problem the central locking does not work any more and I assume that is causing the problem.

A lot of faults with the electrics on my car, so the links you have giving me are brilliant. I will let you know how i get on,
Thanks again
