We have a 2005 Dodge Neon SXT. We went through a couple week stretch where every day or two the battery would die and the car wouldn't start. We had just bought the car from a used lot, so I thought maybe the battery was old and bought a new one. About 3 or 4 days later that battery was dead as well. I took the car to a neighbor and we ran some test on the car and found that when we removed fuse #4 from the fuse box, the draw on the battery was gone. I have had the fuse out for about a month now without any problems at all. Unfortunately that fuse controls the power locks, dome light etc... So its an inconvenience. I'm not sure how to fix it so I wanted to put the question out there and see if anyone knows what the solutions is. By looking around it seems to be a pretty common problem. Thanks!
Fuse #4 Killing Battery on 2005 Dodge Neon

Sounds like there is a lamp small lamp on somewhere. Here are all of the components powered up by Fuse #4. The Radio, Instrument Cluster, Dome Lamps, Cargo (trunk) Lamps, Compass temp mirror, Trunk lamp, Sun Visor vanity lamps, Remote Keyless Entry Module, Sentry Key Immobilzer Module. The best way to isolate the draw is to put a Multimeter across the battery reading Milliamps and disconnect each individual item, ie, bulbs etc, until the draw is eliminated. Check Cargo lamp and Glove Box Lamp (if equipped). Normally, your vehicle should not have a "key off" draw exceeding 30ma. One word of caution. Depending on your multimeter, opening a door can cause enough current draw to blow the fuse in the multimeter.
I have a 2001 Dodge Neon. Four years ago, 90000 miles, the new battery was dead each morning. After trial & error with the fuses, I found it was the fuse that controls the dome light and the radio-cassette player, Rather than hope the mechanics could find the short, I took it out. So I don't have a radio, and I commute 180 miles each weekend!
