Question about 2004 Chrysler Pacifica
The battery goes dead on the2004 pacifica. The dealer checked the charging system and the battery and found no problems. Every month or so the battery goes completely dead. The dealer told me they had 3 other pacificas of the same year with the same issue. No corrections have been found that they know of. Jump start the car and it does fine for a couple weeks. Some times it goes months before the issue occurs.
There is obviously a draw from somewhere, and if your dealer doesn't have a mechanic who knows how to narrow it down to the circuit causing the problem, then I'd question there ability. With that said, when all else fails, you simply remove negative connection off battery first, then positive. Take a 12 volt test light & secure one end to the + clamp or connector, and the other end to the battery+ post. Now connect your negative back up to the battery as it was. If that test light, lights up, there is a draw. It will be brighter, the more draw there is. Your going to have some, just from your radio memory alone, but now comes the fun part. All you do is pull the fuses one at a time, if light goes out, or dim's you've found a draw. When you have a real hard one to narrow down, you make sure you know where they all go back to, whether by your map at fuse box, or your own notes, and you pull them all out, and light should go out for sure, if not, there is another circuit or panel, or relay drawing the current. If it goes out, you start putting them back in one at a time, and when the light comes back on bright, you found the circuit. Mark that one down, pull the fuse back out, light off, now do the rest that you haven't checked yet, just to see if there is more than one draw causing the problem, if there is, mark it down, pull it out & continue on until all done. Now you/they narrowed it down or isolated the circuit causing the problem.
