hi all, after some advice on removal of heater matrix on 53 plate ka sport,
im getting hot pipes from the engine to the heater control valve and through the bulk head but am getting no hot air out of the heater inside the car.
i thinking of taking the heater matrix out and giving it a blow through with hose pipe or would it be best to remove the control valve and stick a hose pipe on it whilst its all still in place.

any advice is welcome thankyou simonxr
