Peugeot 806 AC failure

My Peugeot 806 (2000, diesel) AC stopped working. It doesn't cool, and the system won't switch on. Could it be the AC valves? I checked the temperature control and AC relay, and they seem fine. I don't think it's the pressure switch. What else could be wrong?

That sounds familiar. I had a similar problem with my Peugeot 806. Did you check the AC maintenance records? Maybe a fuse blew? It sounds like the same issue.

Thanks. The fuses seem okay, though. Could the valves really be the problem? What kind of costs should I expect?

In my case, the valves were the reason. The repair cost about 1000€. I'd recommend a workshop for a diagnosis. It's hard to say for sure without looking at it.

Thanks! I'll take it to a workshop ASAP. They also suspect the valves, estimating around 1000€, like you said.
