2011 Honda Civic LX 1.8L with ~ 210k miles. A/C stopped blowing cold air last summer. The large relay was replaced which got the A/C going again until a few weeks ago. Now the problem is that the a/c will work for ~ 10 minutes or so & then will stop blowing cold air. The small relay was replaced but did not fix the issue. Was told that compressor clutch is worn out causing resistance to increase after running a bit which results in the relay being very hot to the touch. Therefore, the compressor should be replaced. Is this a plausible diagnosis? If so, then the clutch can be bought from Honda I'm pretty sure. Would the system even have to be opened up then? If so, I assume best practice is to always replace the receiver drier especially since never opened (I'm pretty sure). I don't see any reason to replace the condensor since this was not a catastrophic compressor failure. I assume that the system would need to be flushed though as a good rule of thumb. However, I can't understand a reason to replace the expansion valve in any case unless the diagnosis was bad. BTW, if the compressor needs replacing, then the plan is to go with a new Denso unit from parts store (AutoZone perhaps). Receiver drier would come from Honda. What say ye? Thanks.
