renault 19 chamade heater matrix?

Hi,
my car is Renault 19. The heater is working but no heat coming out from the heater, just cold? Even i have drove on a long journey but still cold coming out from the heater.
I have checked for the amp which was in the fuse box and no problem.

Trying to remove airlocks in the system won't work because when the water leaks out, air leaks in. Try adding radweld or another patent leak sealer to the radiator fluid. If that doesn't work, you need a new heater matrix. It is easy to replace once you've removed the dashboard... No easy answers to this.
