The windows on the drivers side and the two back windows all fall down. The only reason the passenger side isn't falling is because the window isn't on the regulators. I had to buy new regular clips that hold the window because the entire window had fallen into the door but we have put it on yet. I don't think I have the same problem with the other windows because they would've fallen all the way down too and not come up. The other 3 windows fall down out of no where but they go back up once I turn on the car and raise them. My best guess is its an electrical problem or some signal is given out and they fall down. I don't know if they fall down or just go down as if they where purposely being put down ( with the controls .) I've never witnessed it. All I see is the next day they are all the way down. This actually started happening once I bought a new battery for it because when it was sitting there without one this problem would not happen. Please help out, thanks!
