Hi it sounds like you have either a flap motor or a temp sensor issue on the air con system. To confirm this you will need to have the fault memory of the air con system checked for and stored fault codes. If there are no fault codes stored you will then need them to check the live data to make sure that all the sensor are reading the correct temperature.
I hope this helps and if I can help further please feel free to ask
ill plug the computer in tomorrow see what faults acur thanks fraser
Hi please let me know how you get on with it.
