Have problem with engine overheating and AC cuts off. Fan comes on with AC but when hot seems to shut off. Don't hear fan after shutting motor off to cool engine like it used to. Temperature gets hot enough to shut off AC.Don't want to burn up engine..I understand that there are many sensors so I ran the fault codes-- Got one fault #414--drivers side interior temperature sensor- But I don't think that this would cause the engine to overheat? Does anyone have any info on where the sensors are in a '94 850 turbo?
Just had the knock sensors replaced at the Volvo dealer(ouch!) and know the gas mileage is down. From reading info on the net, I wonder if they have done something to the ETC sensor,which I read is near the knock guys.Does the ETC sensor send out an error code?
From reading the posts I know that KlausC is very knowledgeable about these cars!Maybe he has suggestion or info to help me check out these AC sensors? My head hurts! Help!!
