w124 electrical gremlin - auto antenna and door lights

[richard28]

1993 300ce convertible.

The courtesy lights/puddle lights in the front doors stay lit, even when the doors are closed. Door switches are good, I swapped them out. The auto antenna motor keeps cycling. So I disconnected the plug on the antenna. Now the courtesy lights work properly. What would account for this? Is there a common relay or electrical connection besides the Fuse?

Under the left rear seat there is a convenience control unit, check it for water damage.
