Window Indexing
 

First post on the forum. Our 2002 XK8 coup keeps loosing the window index info after a day or so and then requires reprogramming per the manual. Drives you crazy after a while! Any ideas folks?
Thanks

This often takes place when the battery voltage is not maintained. When it goes below 10.5 volts your windows will loses memory

May I suggest that you take a moment and see what is on out FAQ @ https://www.jaguarforums.com/forum/s...ad.php?t=29800
