Bad Am reception
Before you replace the antenna amp, try running a ground wire from the rear right passenger pillar (where you can easily drill a hole and scrape the paint off the frame as opposed to trying under the headliner) to the antenna amp fastening screw. Looking around where the antenna amp mounts there was no bare metal for a good ground. I tried scraping around the mounting area, but still couldn't get a good ground. The jumper wire was easier and faster. Now my reception is excellent and doesn't drop out.
