There are separate heat box valves for each side...sounds like one side is stuck directing heat to the cabin...these get rusty and stick easily. The boxes are located forward of the heat exchangers under the car...may respond to a little oil and some manipulation by hand while an assistant moves the lever in the car. You can also check for the correct movement of the cable.

Check the heater air valve under the car on the right hand side. It is probably stuck in one position from rust.

hi and thanks, no the heat box valves work perfectly same cables (((
(i have "rebuilt" the silent block front and rear, the shock abdsorber ect ect less than a month ago)
- the whole right side begins to heat up and blows hot air after 10/20 km from the start and seems to do more now that gets cold (now 10C°/50F...10 days ago 41C°/106F...north italy...not south italy))

Do you have heater levers in the front of the box with the fan control? One or two levers?

on the dashboard i have ONE level for the fan (84/86 i suppose) this fan run perfectly

mmm...if possible on the box valves...is not perfectly open/closed? or failed internally...

I was talking about a lever on the floor, by the handbrake.
