Default Drivers window and sunroof not working all of a sudden

Bought this car a few weeks ago and a few days ago the drivers window stopped working and the sunroof won't stay open longer than a few seconds. My first thought was a fuse for the drivers window but I do hear a click when I push the button. Also been having issues with the locks, got the key fob working briefly but even when I lock/unlock the car using the key, the drivers door is the only one that locks, the others have to be done manually. I got it booked for window tint next week so I'll have to cancel that if I can't figure out the window by then.

First try a HARD RESET before anything else.

Then worry about BCM or door modules etc.

So like disconnect the battery? Guessing that would be a hard reset.

From my MXAD student guide Jaguar Training.

Jaguar also has recommended at times to 'short' cables with NEGATIVE cable detached and shorted to positive for a brief period.

Either way is a HARD RESET.

Just for anyone searching for this same issue in the future, the hard reset worked for the window/sunroof issue. Thanks everyone.

Thanks for confirming, so many threads are never updated when things worked.

That's true!!!! Sometimes when the issue is resolved members
may fail to update the thread. It would be nice if members posted
the resolution to various issues such that everyone could benefit.
