Last week I noticed the interior fan running at wild & various speeds after the car had been shut off - figured it was a courtesy/ventilation/computer cool-off thing and not paid much attention (It's been rather warm here recently). A few days later I'm stranded w/ a dead battery. The battery was 11 mos. old and was cratered and was warrantied by BMW. Swapped out battery - car ran like a raped ape. Three days later after much driving - dead again. Alternator shows weak - only 12.32v during idle. Rebuilding alternator today - after battery was COMPLETELY drained overnight. Any thoughts, ideas, suggestions, comments, input, illustrations, technical wizardry, hyperbole, ranting, words of comfort and solace and/or your grandma's favorite pie recipes would be appreciated.
