We are all in a flap
The flap is there to change the direction of the airflow into the heater - when it's open it allows air to be drawn in from outside - when it's closed it recirculates the air from within the car. But what I'd really love to know is what reversing has got to do with it.
If your going to disconnect it the flap is best left in the open position - so in warmer weather (whenever it arrives dear knows) you can have cool fresh air when required.
