2005 XK8 convertible. When I open the door and the window drops a little bit it won't go back up when I shut the door. The left time this happened my shop just had to "reset" the window? How do I do that to see if it will fix it again?

 

Run the window and hold the button until the window stops moving and you hear a click about a second later. You need to get the click in both directions.

 

Get battery tested. Most garages will do it for free. If it’s old, just get a new battery. If car isn’t driven often, get an intelligent battery minder/tender to keep the car battery charge up.

If situation continues, you have a battery drain somewhere. Pull fuses until you see current draw is low approx. 150mA
