G'day! I have a 2004 Sportivo and the driver's power window has been mis-behaving since I got back from an overseas trip. It now feels like there is a limited amount of available power in the motor when I hit the button (almost like it's on a battery). Even with the engine running, I couldn't get the window down and back up in the same go. It will go all the way down and then die on the way back up. Then I'd have to wait 10 minutes and it'll come back to the top. If I leave it another half-hour I can put it all the way down again. And if I push it all the way to "auto" when closing, it'll go to the top and start coming back down again by itself before it dies half-way again! Does this sound familiar to anyone? Am I looking at the battery? The motor? Regulator? Any thoughts are much appreciated. Thanks, T
