Seat Alhambra 7N – Windscreen wiper motor without function

Hello, it’s about my wife’s car. It’s a Seat Alhambra N7 bj 2011. The error is the following. The windscreen wiper motor has no function and cannot be activated. I changed the windscreen wiper motor completely with bars by a new model. Yes also the plug is connected correctly. Only the new windscreen wiper motor does not work when the steering wheel lever is operated. -But I have to mention that the rear flap no longer opens and closes. -The left sliding door does not pull the door completely. -The windscreen wiper engine at the front has no function. These errors suddenly all came together! Who could help me here? Very important is the windscreen wiper motor first of all!
