i have a 1998 infiniti i30 with 127,000 miles on it. Recently, the battery died so i bought a new one. A couple weeks later the new battery died so i brought it to my mechanic assuming it needed a new alternator. He said it wasnt the alternator after he tested it, so he blamed it on a bad battery terminal and replaced it free of charge. A couple days later the battery dies again, this time while i was parking the car, i noticed my speakers shut off and the dash lights started dimming. When I shut the car off, naturally, it wouldnt start up again, so I brought to a different mechanic and this one said that my door switch, which had been blinking on and off while i was driving because the switch was making bad contact with door was causing the problem. He said when i park the car at night the switch would contract (because of the cold) and turn on overnight, draining the battery. The mechanic shimmed the switch so it wouldnt come on all the time. Two days after i picked the car up, the same problem happened. I was parking the car, the speakers shut off and the dash lights started dimming, so of course it wouldnt start up again. This is currently where I stand with the car and any help from experienced mechanics on here would be appreciated
