Hi guys,

A garage in my home town did some serious work on my disco and had to drain the aircon. They forgot to refill it and I was unaware until it got hot:mad: Sent it to a land rover specialist for a full service and fix a leaking centre diff. came out all all was good in my world for a few weeks:D then it got to the point it was oober hot so put the aircon on to find it blows warm. tried the heating and that blows hot for about 15 mins before going cold. To top it off the aircon fan is continually on(my bearmark diagnostic kit is on route for that one).

I have checked, drained, refilledand bled the coolant system. What can I do next:confused:

it could be a servo motor of the flap system sticking and it doesnt close the hot air duct when it should(the matrix is constantly hot, the warm air must be blocked by the flaps on cold comand)... run a manual diagnostic on the aircon system, maybe u get an answer
