Could any one shine some light as to why my heaters don't blow warm air out ...well they do after an hour if not longer ?
The temp gauge goes to half way all time ever under or over but it only takes 5 min to get to halfThay take heat from engine coolant..
so cold coolant -cold air
Thermostat probably..what does temp gauge show..?

Does the fan work properly? Just asking as this is a point of weakness, wiring and resistors fail.
Also have you ever replaced the pollen filter (behind the heater matrix - see here: https://www.fiatforum.com/grande-punto-guides/149411-how-install-replace-pollen-cabin-filter.html) that can stop airflow
