Probably no linkage there. For the cruise control, I would remove the circuit board and resolder every connection on the back of it. This has worked for me on at least two cars that I can remember. Bad solder connections are almost impossible to see even with a magnifying glass. So resolder all of them. Get yourself a pencil type of soldering iron.

As for the antenna, first thing I would do is determine if the thing is getting any voltage.
