I hope someone can help with a factory alarm problem on my '85 300SD. It
has started going off for no apparent reason and using the master key in the
trunk and the doors will not silence it. I assume some relay has failed.
I don't need to fix the alarm, I just want to disable it. I have pulled the
electrical connection to the trunk vacuums diaphragm. I have taken the
fuses out for both the horn and the locking system. Nothing stops the horn
and lights from blaring whenever I open a door.
Can someone tell me where to look for the alarm itself and how to disable
