Aircon stopped working + rattling noise
Driving along yesterday in my 2008 8th gen 1.8 petrol with the climate control set to Lo and I adjusted it up one notch and the air suddenly starting coming out hot. This was unfortunately 10mins into a 3hr round trip. The aircon wouldn't kick back in for the rest of the trip so sweated it out.. The fan still runs when you turn it on so I know that is working.
At low speed (it might be there all the time just not audible) and when idle I could hear a rattling / oscillating type noise (with climate control off.. no air coming out). I don't hear this at all if I turn the engine off and turn the air/heating system on (although no cold air still).
I'm not sure if this noise is something in the aircon/heating system, but weird this would start just as the airon breaks. I tried the aircon diagnostic thing and it came back with 88 on the code. I replaced the aircon relay a year ago, so not expecting that to be the issue again (particularly with the rattle noise that is new).
Does this sound familiar or identifiable to anyone? Am i barking up the right tree that the two are related or could the noise be something else? Wondering whether to take it to an aircon specialist or to a general mechanic..
