Wiper issues 2015 smart fortwo pure hatchback 2dr

Hello, I have a 2015 smart Fortwo Pure hatchback 2DR.
After starting the car, when I turn the light switch on the wipers go into intermittent mode and stay in that mode as long as the headlights are on.
If I do not turn on the headlights the wipers do not turn on unless I turn them on manually and they work as they should!
When the lights are on I can still change the wipers from intermittent mode to normal or fast mode but they default to intermittent mode and in the off position they still work in intermittent mode!
Also a new issue, when the light switch is on and I put the car in reverse the rear wiper will turn on. But the rear wiper will only turn on when the car is in reverse not in Drive. But the rear wiper can still be operated as normal in drive mode.

I have disconnected the battery and let the car sit but after reconnecting the battery the car still does it.

Thanks for you help!
