Last night l opened the driver’s side window, it went down ok, but it now won’t go up. The window is now in the down position.
When l push the window switch, in the down position l can hear the motor clicking. But when l push the up position l hear nothing, so l suspect it’s an electrical faulty.

Has anyone had the same fault, could it be a fuse?

If you can hear the mechanism trying to do something, it suggests that there is electricity getting there but it's not raising the window. So I'd pop the door trim panel off and have a look.

Occasionally I've had fuses not exactly blow, but develop a very high resistance. So the voltage at the component itself is not enough to activate it.

But I'd have a look at the window mechanism first. Maybe something has jammed or the motor is struggling.
