Start by checking your coolant level and antifreeze strength is up to scratch , Also check engine is reaching working temp . and hoses into heater matrix are both hot

Hi yeah it's all as it should be, a mechanic mentioned it being a flap in the heater box. That will cost a fortune to repair 🤔

If both hoses through the bulkhead are hot . it could only be the heater flap actuator or more likely , heater control valve which is not a big job
