BCU goes crazy

Hi guys,

It s really annoying what s happening to me right now, i ll try to explain with all details. Starting some weeks ago, after it s raining my car goes crazy. What i noticed first, the wipers start work even if i m out of the car and the car is locked. The wipers stop just when i turn the 2nd position of the key. First i thought it s the rain sensor failure but past days i noticed even the interior lights turning on and off many times alone, the drivers windows switch not working anymore, but the windows are working if you use the other switches. Now i have to disconnect the battery all the time and after i reconnect it and turn the ignition on, one of the windows randomly goes down. Moreover i cant lock the car anymore through buttons of the key, the car do the horn noise as a door is opened. And if i can succed closing it like that, in some minutes the alarm will start alone and will not stop even if i turn the ignition on. It happened two times for me until now and everytime after some days after the rain, if it s hot outside the car work as before, without any problem. All the time i checked the ECU that is placed under the windscreen and notime it wasnt water there. Did anyone faced with such a problem ? Thank you a lot for your answers.

Sincerly,
Andrei.
