This is a bit presumptuous since I've never seen a '90 Euro-spec
Doka...but anyway on the regular ones:

The top lever controls airflow to the windshield.  Right is more.

The second lever controls air temperature (including the side vents
on later ones).  Right is hotter.

The third lever controls airflow to your feet.  Right is less.

(And the fourth lever controls unheated airflow to the rear cabin roof vents.)

There isn't any control on air into the system, only on air leaving it.

So if you don't want heat, second lever all the way left.  If that
doesn't shut off the heat you can replace the heat valve or install a
shutoff valve in the line or pinch the line shut with something that
doesn't injure it.  A pair of small wooden blocks with edges rounded
over, clearance holes in one side and pilot holes in the other,
screwed down over the hose would do it.  Just remember that the space
between the screws has to accommodate the hose width when it's pinched flat.

Yrs,
