Taxi Etiquette

The driver who picked me up had the heating on full blast and also stunk very badly of BO to the point that I wanted to stop breathing. I wound the window down for some fresh air and he immediately pressed the button to close it. What’s that about? I keep opening it and he keeps closing it without saying a word.
Now I am sat here with it full down and my finger depressed on the down button to stop him closing it but we’re on the motorway and I’m getting blown all over the shop. What’s the correct taxi etiquette apart from not tipping?
