2019 NISSAN ROGUE Visibilitywiper Problems

The heating/cooling do not operate correctly on the driver side or rear passenger vents. Proper temperature comes from the passenger side vents. Local mechanic attempted swapping the blend door actuator and then it failed again. My mechanic then said that I would need to replace the entire Heater / AC Unit Assembly. After searching online, there are multiple forums dedicated to this same issue, specifically for VINs that start with KN. This is a safety issue because the defroster does not work on the driver side, it blows whatever the ambient air temperature is, so in the winter when the windows fog up the drivers view is impaired. There are no warning lamps message or other symptoms.

THE SIDE REAR VIEW MIRROR ON THE DRIVER'S SIDE IS EITHER TOO BIG OR IN THE INCORRECT LOCATION. IMPOSSIBLE TO SEE THE LANE OF PERPENDICULAR TRAFFIC CAN TURN TOO DEEP VERY EASILY . HAVE ADJUSTED THE SEAT IN VARIABLE WAYS TO SOLVE THE PROBLEM ,NO LUCK. #2 THE PRO PIOLOT WHEN IT IS TURNED ON I HAVE TO FIGHT THE WHEEL GOING DOWN A STRAIGHT ROAD I85.EG.) IT TRIES TO STRAY FROM ONE LINE TO THE OTHER , LIKE A SNAKE GOING FROM ONE LINE ON ONE SIDE OF THE ROAD TO THE OPPOSITE SIDE OF THE LANE. SO I PAID FOR AN OPTION I CAN'T USE.BUT THE MAIN THING IS THAT BIG BLIND SPOT WHEN TURNING LEFT, YO HAVE TO LOOK TO THE RIGHT SIDE OF THE CAR AND GET HAS CLOSE TO THE RIGHT ,NOT STILL NOT KNOWING IF YOUR CROSSING THE CENTER LINE OR LEFT TURN LANE...
