Do a pressure test when cold, if it's losing pressure at least you're searching for the escaping water round a cold engine, if you can't find the leak add tome UV marker and look with a black light.

None if the vehicle's level... if you're worried support the centre with a jack when you unbolt it from the chassis then you can release ant tension in a controlled manner.

Our local mobile AC guy can't do those repairs yet unfortunately.
Though our local LR dealer came up with a price a good bit less that the online sellers have it listed at.

Just been trying to fix one here, no sign of any bad joints and everything was working fine with the board out of the housing... put everything back and no rear windows again
