I got the car May 25 - about 2 weeks later, the battery died. I put in a new battery. About 2 weeks later, the battery died. I got it recharged, it lasted about 2 weeks. I did this a few times before I got a new alternator. About 2 weeks later, the battery died. I had the alternator, battery and wire from the back of the alternator checked. All okay. The lock had been sticking on the drivers door. Mechanic thought that it was the battery drain problem. He disconnected the electric lock. 1 week later, the battery died. I keep getting boosted and recharged and am now beyond frustrated. The AC quit just before I bought the car. The back windshield defroster doesn't work. The passenger window is incredibly slow, up or down. Other than that, it seems that everything works. At least once, the dome light came on by itself. I need ideas of where to have the next mechanic to start checking because it cost so much. Any ideas?
Yes. You just need an honest, qualified mechanic. I'm not saying your last mechanic was not qualified, but any mechanic should know how to search and test for an unintended drain. Sounds like that is what you have.
Go on youtube and watch videos of "unintended, or parasitic drains"-there are hundreds of them. Any mechanic with a good multi-meter should be able to find it pretty quick-within an hour or two.
I wouldn't worry about the AC-your car is too old for it-too easy to have problems with a car that old, although if you have enough money, you can do anything. Just saying it would be expensive. The window problem is not an expensive fix, probably needs a new window motor. yours probably has worn brushes. The rear defroster is easy to troubleshoot with a multi-meter. Keep at it and you will have a good car.

maybe the wire is severed where the door (drver dr) pivots. thats what was wrong with mine. there is a rubber boot with crinkles in it that hold all the wires together. you can also try replacing the switch board that controls the wndws on the drvr dr. hope that helps.

Follow the red wire from the battery towards the firewall. It will end at the starter.

have you checked the glove box light? another way to tell where your short may be is to hook a voltage meter to the battery and notice a drain on the battery with the key off! then start pulling fuses to see when the drain stops and that will narrow down the possibilities of the problem... the drain should be easily located if its killing the battery overnight... help this helps

Connect a 12 volt DC test light between battery cable & post on positive terminal.(remove terminal) (inline) When that light is on, there is a draw. Radio memory, alarm/antitheft systems, etc will cause a draw, so make notes & pull them first. Light will be dull on low draw, bright on high draw. Watch light closely & start pulling fuses, when you see it dim down,or go off you;ve found a draw. If no change, put it back in & continue. I usually start with the suspected draw spots like listed above, and accessories fuses.(like a cigarette lighter stuck in.) If all else fails, I've had to remove all the fuses then start replacing one at a time, until light gets bright, to point me in direction of major draw. Don't be proud, if you don't think it's labeled well enough for you to remember where they all go, make your own drawing & notes. Keep me posted of your progress.
