My radio/clock display works when it wants to. My auto. trunk release works when it wants to. My "door is open" and "you aren't buckled up" chimes work when they want to. They are not on the same schedule, working and not working in no particular order. Is this a short, and is it likely one short or more than one? Thanks.
A short is a path where excessive battery current flows, without going through a light etc to limit the current. Fuses blow when shorts occur, to prevent a fire. Since you aren't blowing a fuse, the problem is probably open circuits, where a gap occurs blocking the current. These are generally caused by corrosion or vibration. I would start checking the ground wires of the failing stuff. The copper to steel connection is vulnerable to corrosion & intermittent connection. Trace the circuit from your factory service manual, and use a test light. Bruce Roe
Check for anything metallic in a cig lighter. Make sure your "body" fuse isn't blown.
When I was driving 80's Eldo's as everyday cars, my son dropped a penny in a lighter socket. I removed the lighters so the kids wouldn't hurt them selves.
After that, I also removed the power wire from the lighters after replacing the body fuse.
You also can have dirty ground connections.

Rick,
You will need to find a common point that these connections may share power from; in your case it could well be the ign switch, as it is the main key for these circuits to work.
Possible duty or weak contacts at the ignition switch, loose connections, etc.
Good luck..!
