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..

Thanks,

John

Have found a youtube video which has the pretty much same sound I'm hearing which suggests belt tensioner is the issue..

I can't post links but if you google for:

08 Civic rattling noise coming from tensioner - YouTube

It should come up with a 2m5s video from 23 Mar 2014 by SpecialKspb

Is this an expensive fix?

Thought i'd provide an update incase others come across this in the future.. Had it looked at by a mechanic friend, and the aircon compressor clutch has broken up apparently. It doesn't look like you can get just the clutch OEM (Lings have it listed but at a similar price to whole compressor OEM) so the whole compressor is going to need replacing and its about £285 for and probably about £500 all in once for labour etc once replaced / regassed :-(

that's what was originally wrong with mine a few years back so i bought a guaranteed second hand compressor for £80 ,took it to my mates garage only took 20 mins to change over then had it re-gassed and all was good..

Sounds like a cheaper way to do it..! If I had the time I would look at doing that. I did find a cheaper part (~£160) but I think it was coming from Germany and was going to be next week when it gets delivered, but I can get this replaced tomorrow with a next day part! The price you pay for speed I guess..

Waiting for a replacement compressor for mine as well. Bought it from autodoc in germany as not paying what Honda want for a new one.

I miss aircon. Mine broke the first day it was really hot lol.

Then run it a bit throughout the cold periods to stop things 'drying out' or whatever. I rum mine all the time. Helps with demisting during cold periods.
Does it make any difference to my fuel consumption? Probably, but I haven't noticed any. But either way, it will cost a lot less than having your aircon repaired.:smile3:
