its a ford ka 2 1998 s reg and it has started blowing out cold air, i had the thermostat changed but that was not the problem as the old one wasn't even broke. my dad then went to check the heater control panel which when he tried to undo the factory clips the pipes to the heater control panel fell apart, we have ordered a new heater control panel which wont be delivered till tomorrow, could this be the reason why it was blowing cold air out? as the car is quite old and the plastic pipes had perished.also can anyone give me any tips how to drain and refill the coolant system when my dad is fitting the new heater control panel? thanks
