One of two reasons...or maybe both:
The reason they do not work is because they lost the programming. You have to hold the power window switch in the up and down position for a few seconds and the use of them will return. The time of lost power caused the programming to go out on these items.
take it in to have the codes reset. they were set off with the battery change.
What you probably need to do is to check you battery because i have a dodge 2004 also and my locks did the same thing so i just replaced my battery and the locks started working again.
Check your fuses.
It can be your battery, when it doesn't have enough power the computer will not allow you to use power stuff. It can be also one of the relays which are responsible for stuff like power locks, power windows and so on.
you can disonnect the white terminal from the battery clamp but then the windows do not work. the locks often stick on and drain the battery. so i would like manual locks just turn the key. tell what to disconnect
you need to reconnect the battery
Check the fuses.
a loose or dirty electrical connection
Your car won't start. No electrical items will work (radio, lights, power windows/locks...)
Start with checking for blown fuses.
The 2005 Dodge Caravans have software problem in the BCM that causes the power locks to quit working. The only fix is to bring the van to a dealer for a software flash update.I disconnected the battery cable and pulled the BCM fuse and the system reset and the door locks are working fine again.I also got my power door locks working. I pulled and reinstalled (but did not replace) all fuses and fuse blocks (but not the relays). The locks started working after that.I'm not sure if I'm using this site correctly as I'm new, but I found that disconnecting and reconnecting the lamp and horn relays fixed my same issue with the locks.Several people suggested resetting the fuses under the hood, and it worked. Others tried unplugging and plugging back in the battery and that also worked for them.I tried the suggestions and it worked for a short time, but now the locks are not working again. Funny thing is that the rear hatch locks still work, but all passenger and driver locks do not. Time to take it in and have a pro fix them? Resetting the fuses and relays doesn't help anymore.
There is a Relay for the Power Door Locks, which I purchased today from Checker Auto parts, but I can not find where the relay is located. I am assuming or hoping that it is the Relay for both the Door Locks and Power Windows.
