Tried posting this earlier but cant find it


We have a launch edition Abarth 500 with climate control


Its developed a mind of its own, heat is fine initially but it slowly looses heat no matter how high the temp is set. bring it down & air con is fine


A search of google shows 2 things, it may be a complete heater unit replace at 8-900 pounds + labour.


On some fiats there is a reset procedure by holding down 2 buttons


Is there a reset on the Abarth , or any other thoughts other than a complete unit


Any help appreciated
