So I have a 1988 Automatic Trans Am with that lovely 305 TBI Shitty design. I had the car for a few months then out of the blue my door locks keep locking on their own over and over again (Driver and passenger). I pulled the fuse it stopped but then I also my radio no longer gets power nor does my small interior light on the top. So put the fuse back and and then I replaced my battery and it stopped but then it started again the next day. My Voltage stays right in the middle, but when i go to start the car the next day my voltage got low and then soon the battery was dead, which is why i got a new battery, So I unpluged the battery for about a half hour or so reconnected it and its not doing it but I have a feeling ither in the morning or later on tomorrow its going to happen again. Any Advice?
