Ok, this isn't stereo or communication, but it is electrical (and mechanical). Is it possible to modify the rear door windows so they go down all the way? I have taken apart the door to see, it looks like it can be done but I wanted to know if anyone has done it before? -Thanks

I dont know, but would be absolutely interested if someone has done this. That 1/5 of the way that they don't go down cant do anyting but piss me and the guy in the back seat off. If there is a rubber puck at the bottom of the track, removing that may be all that is neccessary.
Im sure that there is nothing more than that type of governing device which keeps it from going all the way down.

I'm not a techie but looking at the shape of the inside of the rear door, it doesn't look like there is any more room for the window to go down before hitting the bottom the the available space on the inside where the door curves for the rear wheel. Open one of your rear door and notice the available space inside due to the door shape--there's not much room.

If I remember correctly there is not enough room in the rear door for the window to completly roll down. Try a search, I'm sure someone else has asked that question.
