Air Con Clutch faulty - Honda FRV 2.2 2006

[Bobbybiscuit]

Had a man check air con as not working - air con circuit dead to air con clutch. I then recalled that I had a error code reader although no fault on the dash appeared. Code P645 is the error code. So where do I go from here. 

 

I do recall several months ago the crunching of something and when turning off air con it went away. So I left it off. Recently turned on air con and no noise but no air con either! 

 

What needs to be replaced please and anyone know the part number. I think it is the air con clutch assembly but can I find one...no I cant ! 

 

Thanks

Have you tested / replaced the Air Con System Relay, which tend to fail.

Then you will need to follow a process to reprogramme the air con system....can be found on YouTube.

The bearings tend to go on these usually you get a grinding noise when you out the AC on. Mine is doing it now ! Maybe yours passed that stage. you can get new bearings and it's a pretty straightforward job.

Looks like your right that. I am not that handy with cars so i will ask my garage I use to carry out the repair.

Thanks for the  input from both of you here.
