2005 Pacifica electrical issue
Hi, my mom has a 2005 Pacifica with an electrical issue. The other day, she took the dog for a ride and everything worked fine.
Today she goes out and her fob wouldn’t work and the car wouldn’t start. Turns out the battery was dead. I jumped it, then took it for about a 20 minute spin. Parked it, turned the key off, opened the door and the radio stayed on. The radio should turn off once the door is open, right? Is there a switch in the door that could be causing an issue, or maybe a BCM? Something is draining the battery. I did check to see if she left the lights on, and they were off. Could a weak battery cause an issue like this? Any ideas? Help is appreciated. Matt |

Going to take someone with electrical experience to identify the root cause. Quite a bit involved, attached is a partial wiring diagram.

Still dealing with the issue. With everything going on, haven’t spent much time working on the car.
I watched a good YouTube video about a Pacifica with tons of electrical gremlins. Turned out the issue was with a ground wire that was below the battery tray. I looked and the wires were crusty green, so I put on a new eyelet connector. That didn’t solve the issue. So maybe the next step is looking at the drivers side door switch. I will let you all know what I find. |
Had the same problem, dead battery, had to recharge. I believe it's the ignition switch. To prevent it, I turn the car off and jiggle the key until radio goes off.

Did you get this resolved?
Were you able to solve problem?
I have a parasitic draw and believe it's my ignition switch.
Thx Rich Ard |
No never did any troubleshooting, car is old so I just do the jiggle thing, make sure radio goes off, and then pull the key. After repairing the problem with main ground wire issue, pain in the neck to get to, don't want to do time consuming fixes. (although maybe easy fix?)
