I have a 1986 300E. Is there an easy way to test the warning module/buzzer?. My does not work. I do have the Electrical Troubleshooter Manual but, it is not clear enough...
TIA

I have the car for about 4 years now. I'd never heard the buzzer since I bouhgt the car, i.e when open the door with the keys in the ignition, lights left on,etc. It was not a big deal before but, the wife forgot the lights on, the battery went down etc.
Any more info you need? TIA

I have replaced a number of these and if yours isn't working it's probably faulty. Do you need to know where it is? In the ETM it has a locater.

Hi Benzmac!
I know where it is. As a matter of fact, I took it out, clean contacts but, it did not work. I was trying to confirm if it is broken or a bad conection/ground somewhere...oh well!!
