Greetings all and a DS5 with non working air con

[Old_and_Slack_900]

First post so please go easy? Ta.

I have a 2015 DS1.6 diesel manual.
The air con stopped working so I’ve checked the usual stuff like the fuse (ok) changed the sensor for a new one and checked the charge pressure which shows as spot on.

When I switch the a/c on , there’s no ‘clunk’ of the compressor coming on.

I’m out of ideas.

What am I missing?

Cheers all

You need to get the car read by a decent code reader, preferably Diagbox, to see what errors are stored in the ECUs. Without those it's just guessing in the dark, to mix a metaphor.

Thanks. Thought as much

Having enough pressure is not the same as having enough refrigerant, there is a chance it may still need a regas but see what the diagnostic shows.
