If you have to keep your window open in the rain, duct tape a folded up cloth over the switches in the driver's armrest. Otherwise you will get the aforementioned streams of water directly onto the switches. They then sot working...
That is why I have one window open in the pic.
The pice of clothe works fine, because the water doesn't flow
