I have recently acquired a ford galaxy 2.3 zetec 1999, first chassis as it's on changeover year. This first problem is passenger and drivers windows go down ok, but I can only close them when I lock the car on the passenger door lock, after a while, the drivers window opens a couple of inches on it's own. 2nd problem is I can't lock the drivers door as the lock spins in the handle with key inserted and I can't manually lock the door from the inside as it won't push inwards. 3rd problem is the interior lights don't go out when ignition on or normal use. Last problem is the wiper arm spindles are worn, is there a repair kit? Any help will be appreciated
