Hi ive just got a DA LTD and the heater only just works, its got climate control and ive flushed the cooling system and the heater core and checked the heater tap and it all seam to be working fine (the tap opens and the two heater hoses that go to the heater core are both hot),but still no heater. Ive been told that they have flaps controled by elec motors witch let the hot air out and ive been told thats the problem but ive also been told that there is a code that you can type in the the climate control unit and it will tell you the part thats broken?? Does any one know this code? Thanks Danny
