So in my 2010 Grand Caravan every so often will lock the doors multiple times in succession, and fast, it does this whether or not the van is on or off. one time the keys got locked in it with it running because I got out and the doors locked themselves with the keys in the ignition and engine running. nobody is pushing the lock buttons either knowingly or accidentally.
My drivers side window also likes to fight with me sometimes too, where I'll go to roll it up and it'll start moving up and then change direction immediately and go back down, and sometimes it'll even start coming back up again but it usually takes me a couple of times to actually get the window to roll up when this starts to happen.

Anybody else had their become possessed?

 

I just watched a video yesterday on the top 5 problems in the dodge caravan 5th gen and you have water in your TIPM. Go to the 2minute mark in this video.

 

well that's weird, I'm not sure how water could've gotten in there if that's the case, it's been pretty dry here, and this problem has been ongoing for quite a while. I don't think I've even driven this van in the rain.

maybe it's not water but it leads me to believe I should look at my TIPM to see if anything is amiss.

 

I really don't have any idea, I just saw that, according to this parts seller, the TIPM getting water inside was a common issue. It could be a magnet for humidity, if the box gets hot inside and the air inside expanded and pushed out, then at night or after the engine cooled the box would maybe suck in cold humid air. But if that were the case why wouldn't it push the water back out when it gets hot again? So I don't know and the video doesn't appear to say how the water got into a box so far up in the engine compartment.
