I have exactly the same problem with both my front windows my 2008 XJ Sovereign. 
Did you manage to resolve it?

I’ve only recently purchased mine and will be looking into it.

Hi,

I have recently purchased a 2008 XJ Sovereign 2.7 and I have a problem with both front electric windows. 
The rear windows work perfectly.

They front windows will only move up or down in short increments. One press to go down two or three inches at a time. But when they go up I have to click at least 8 times for them to move two or three inches. 
Can anyone tell me how to fix this please?
