Battery failed on my 2011 XJL (neglected in the garage - my fault). Jumped. Charged. But then the sunroof would not engage. Found the thread here about pulling the fuse and resetting it. Worked like a charm.

Thanks fo saving me a dealer visit. Always feel good to fix something this high tech myself.

 

And you are reminding me to check on mine, been sitting in garage for 2 months untouched :-( hopefully it's charged, I'll check when I get home, thanks
