the battery began to die; something was drawing power while the car was off. at the mechanic they replaced the alternator, but i was still having the problem. I cant remember if this happened before or after i brought it to him at this point, but the speedometer was at 0, not working at all, and no mileage was being recorded. when they finally did something so that it stopped drawing power, im not sure exactly what it was --he had me get a piece for the fuse box in the hood, and that hadnt fixed it, and he said in the end all he did was take out a fuse.
i no longer had to unplug my batter when i turned the car off, but the speedometer and odometer is not working. he told me to get a speedometer sensor, but needless to say, i have stopped listening to/going to this mechanic.
I don't know a whole lot about cars, obviously, but i know that an electronic diagnosis could run me a lot more, especially because i don't--i was wondering if anyone had clues as to what it could be?
