Heater not working

[Berlingoboy1]

Hi All, I have an 09 Picasso and i'm not getting any heat from the heater, the blower works fine and the car runs perfectly.
The Radiator level is good and rarely needs a top up.
Any help would be appreciated thanks

Check your heater blower resistor ?

Thanks for that answer but I've just googled it and all they mention is the blower not working, mine blows properly but just cold air, is there a valve or flap some where that's not opening which is diverting the hot air and is this all a diy job,

Very probable, someone who knows more will confirm, unlike older cars modern car cooling systems have the hot water running through the heater matrix all the time and just vary the airflow between hot & cold.
When you move the temp adjuster can you hear a flap working.
Another thought, Thermostat, but then again you say the car runs perfectly, but does the engine gets up to temp!
