It would be nice. I use the power 1/4 windows on my van all the time. Sometimes its just the perfect amount of air.
I have seen the power "swing in and out". I have never seen the power "up and down". That would be pretty cool.
dodge caravan 1/4 glass motors and linkage would work. and theyre easy to find in just about any salvage yard
I looked at the caravan rear motor. an it looks like everything else needs a little work but can be done. I'm going to get a hold of one an start working on it. So if you have some pointers or pic of something close to what I'm tryn please post it.
