Subaru Wagon Impreza 1996. Automatic, 1600cc.
- The gas (refrigerant) has been refilled recently, so that's all good.
- The air seems to be colder when the revs are higher (>2,500 rpm or thereabouts).
- But then if I'm idling at a stop, the air seems to not be cold anymore.
I've also been able to make the air colder by simply switching off the aircon and switching it on again whilst driving.
I thought maybe it could be a fanbelt that is slipping, or worn? Do aircon's have fanbelts?
