2005 XJ8L: passenger front window will open but when you try to close it goes up maybe only 2cm then stops and won’t go again.
When I disconnect the battery, then reconnect, it will go up again, same as last time. If I accidentally forget and open the window, I will need to get in and out of the car a dozen times disconnecting and reconnecting the battery as I slowly inch the window closed.
tried replacing driver’s side window and mirror control unit, but replacement is doing the same.
Any ideas what I should do?
