Hi, this is Sweden calling!

I have a problem with the AC in the car. The car has two zones but I cant ger any mixed or cold air, only warm air on the driver's side. On the passenger side the temperature works like usual with hot and cold.

It does not matter if I raise it to the maximum full heat or lower it to maximum cold , the wind blows like hot air from a rocket. However it blows less if you set it to the temperature close to the actual temperature inside the car. At the lowest temperatures, it feels like a warm hairdryer. I have tried to turn off the AC, to let the air recirculate, let in blow only on the window or the floor, close and lock the car and so on. Anyone have any idea!?!?
