Mercedes B Klasse AC Failure

My 2023 Mercedes B Klasse hybrid is giving me fits The air conditioning has completely failed with only 29786 km on it It won't even switch on I've checked the AC button and climate control settings I suspect it might be a defect in the valves of the AC system or a refrigerant leak or a faulty blower motor Has anyone experienced something similar I am estimating a repair cost of around 1000€ Any advice on AC maintenance or temperature control issues would be greatly appreciated I am so frustrated

That's rough AC problems can be tricky Is there any unusual AC noise before it stopped working It could also be a fuse Worth a quick check before diving into more complex stuff

I did not notice any unusual noise but where exactly are the fuses located that control the air conditioning I'm not very good with the technical details can you guide me a little bit

Fuse box location is usually in the engine bay or under the dash The owner's manual should have a diagram But if it's not a fuse and you suspect valve issues honestly it's probably best to get it checked by a workshop They can diagnose any refrigerant leak or blower motor issues too

Thank you so much for your advice I checked the fuses as you suggested and they seemed fine I decided to take your advice and brought it to a trusted mechanic It turned out to be a faulty valve as I suspected The final bill was indeed around 1000€ but at least the AC is working perfectly now Your suggestion to get it checked professionally was spot on
