My trucks an 85 GMC and my antenna is in the windshield. I do know from experience installing an aftermarket head unit, the antenna cord isn't long so it may be unplugged. I got tired of how short mine was and bought an extension. It was so short I had to put in my radio then feel for the cord and hole from under the dash. It's a good place to start though, check for your antenna being plugged up and let us know.

As for the other problems, I'm not sure. Doing the bucket method as you said should find it, get a helper one to pour one to watch! Goodluck
