======================= The event happened immediately after going through a "normal" car wash. The boots screen switch housing definitely had water in it. I now believe because the lid had stopped working some months earlier, that the switch was u/s. When the water enetered, it closed the citcuit and opened the window. Unforunately at the same time it effected other electrical items especially the rear wiper. I have had the car inspected by professional auto electrician (not citroen) who could not find any fault. Incidently it is not now possible to communicate with the onboard computer (2 garages have tried including a citroen dealer). Is it a relatively simple job to inspect the BSI and connections. I do not know where to start. I will start to carry out the "window fix" as sent. Many thanks
