Vel Satis AC Not Cooling

Hi, I'm new to the forum. I have a 2003 Renault Vel Satis with a diesel engine and the air conditioning isn't cooling at all. The system doesn't even seem to be switching on. I've checked the fuses, but I'm not really sure where to go from here. The car has done 183433 km. Could it be something simple like a pressure switch, or maybe an AC relay? Any help would be appreciated!

Hey, I had a similar problem with my Vel Satis. It turned out to be faulty valves. Could be that. Have you checked for any refrigerant leaks? That's always the first place to start before suspecting the compressor or any other component.

Thanks for the quick reply! When you say faulty valves, do you mean individual valves within the AC system itself? And how would I check for refrigerant leaks myself? I'm not really sure what I'm looking for, or where to look, to be honest. Is that something I can easily do, or does it need special equipment?

Yep, valves inside the system. Honestly, unless you're super confident, checking for refrigerant leaks properly needs specialized equipment. Most of the time you can't even see a refrigerant leak. I'd book it into a shop. If it is the valves, expect a bill of about 1000€.

Okay, thanks so much for the advice! I suspected it might be beyond my capabilities. I'll take it to a local garage for a proper diagnosis and repair. I appreciate you confirming that those valve issues are a likely culprit. I'll post what I find out.
