On my 2005 Grand Caravan, I started to have issues with my lift gate.

First I could not open it from the outside, even if I made sure it was unlocked with remote or from the drivers door. It would open if I used the Power gate, just not manually from outside.

Now sometimes when I get in the van, the little icon is lit on the dash saying the back door is open , and when I turn the key on, I can hear the door lock? make the sound like it is "sucking" the door shut/locking it. And tonight when I hit the unlock from the drivers door it made the esame sound, and when I shut the door it did it too.

And..........it keeps getting better. This morning the battery was dead. I came home and boosted it for my wife, and tonight I checked it out after dark and the interior lights, (just the ones in the back were on) and the battery was dead again. ( we had the keys in the ignition, which should not make a difference)

It was after this that I figured out the close the drivers door, hear the tailgate lock thing..............

So, do I have more than one problem here, or is it all back door wiring related?

Thanks in advance, and sorry for the long post.................

( I just replaced a water pump on Mon, so not looking to spend a lot more money )

 

The rear lift gate latch assy maybe keeping the lights on.Remove the rear panel and disconnect the latch assy.

 

ok, sorry for the delay in answering.........

it was .................ready for it?

a poor battery.

seems like the computer goes funky when the volts drop.

Had 18 month free replacement, and only had battery 13 months. Yippee.
