The dome light only work with the right side door open. There are no power to the left door contact switch, hood, and the alarm does not work. Also, the power seat only work if the engine is started, or on ACC.

Benzmac has replied once, that my problem is the buzzer relay, but the buzzer does work to warm to fasten seat belt.

I have reveiw the wiring diagram, but it does not reveiw how it is connect to the plug-in, and to which relay.

Do anyone know if the left door power is from the alarm control relay.

Thanks, jack

If you will replace the warning module, your problems will be solved. The warning module is wired in to the left door only. It is in the wiring diagram.

Benzmac,

You were right! the wire diagram is on book 1 of the classic manual. But there is no picture of how to find the warning. The Houston MB dealers has no idea what I wanted, and I finally pick one up a new one at my regular MB part wholesaler. I removed the driver side under dash cover, but I am not able to find it.

Can you help, where is it?
