Yep, first thing I did was clean battery connections and check all fuses, both under hood and by driver's leg. Even pulled the radio (it is an aftermarket installed a couple years ago) to see if any "obvious" loose wires. Checked electrical schematics to double and triple check fuses that seemed to be to those specific items. I have not checked grounds up by firewall (this isn't my car, so I don't have it full-time to doodle with). The battery did have a weak cell, which is why it was replaced. If everything had worked again that would have solved the problem, but the fact that those items mentioned do not work concerns me. I know a low amperage short can drain a battery slowly and not break a fuse (I had this happen once with an analog clock). The new battery will take a while to drain if that's the case, so I'm hoping for a broken circuit rather than a short. Just need help from you experienced folks on tracking the problem. Oh, and I'm not a young buck anymore, so crawling around under dashboards and hoods isn't the easy task it once was!
Oh, and it just came up out of nowhere - the part where the radio quit working and the dome light, etc. Car worked on Friday, but then got in Sunday morning and a groan followed by the "click, click" of a dead battery (and no radio, domes, etc. when good battery attached) I suspect the battery was dying before that (an Interstate, still two years left on the "warranty"), but it always started normally. I do believe the alternator is charging, starter good, etc. Everything works fine now that new battery in as far as mechanics go. Just not those items mentioned (and maybe others that I haven't noticed on same circuit or circuits)
