1994 Mercedes Benz 320sl 40000 miles
When turned on the radio lights up and looks like it would be working. But the power antenna does not go up.
There is no sound. Not from the radio, CD player, or weather channel.
It seems that the radio isn't sending a signal to the antenna and the amp which are in the trunk.
This is all factory original equipment.
The only troubleshoting we have done is to make sure the connections are all intact. Which they seem to be.
(we have a friend with the exact same car and he is having the same problem)
