Bobbybiscuit Posted August 8, 2020 Share Posted August 8, 2020 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 Bobbybiscuit Quote Link to comment Share on other sites More sharing options...
Trevor Posted August 10, 2020 Share Posted August 10, 2020 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. Quote Link to comment Share on other sites More sharing options...
foursail Posted September 26, 2020 Share Posted September 26, 2020 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. Quote Link to comment Share on other sites More sharing options...
Bobbybiscuit Posted September 26, 2020 Author Share Posted September 26, 2020 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. Quote Link to comment Share on other sites More sharing options...
