My sunroof open involuntarely and it rained into the the cabin 24 hours or so. When i discovered it, i put 3 fans into the car and drained everything for 2 - 3 days ...


But since that, M+S switch blink, and the car goes into failsafe mode in the morning. After 5 minutes driving i can stop and restart the car and everything works again for the full day.

I installed a new XYZ switch last year.

So i guess it's water/humidity, but where???

Never mind where, stick a dehumidifyer in it for a couple of days. Fans will not dry it out
