My tailgate window has been a bit stubborn lately, not lowering sufficiently to clear the top seal. Also I have had to pull the handle twice in order for the door to open. A few days ago I shut the tailgate, without realising that the window had closed outside the top seal. When I saw it the next morning I opened the 'gate and when the window raised to the closed position there was a lot of loud clicking for a few seconds. However, 'tother day it started lowering completely when I opened the tailgate, so I had to raise it with the internal switch, again accompanied by the clicking. Since then it has started to refuse to raise without my wife operating the switch and me assisting it manually. Also the rear wiper has stopped working. The window motor seems to be working ok, it's just that it's playing silly b's. Anyone had this problem?.
