peugeot 406 air-con faults

[KebabMeister]

Can you be more specific?  Has it totally stopped working?  When engaging the air-con can you hear a drop in engine power and a loud click?  Is it climate control (with digital reading?).

Although you say the fuses are okay, is there live at the fuse box?  If there is live then you need to check if there is a relay or air conditioning control unit.  This will either be next/near the fusebox or under the dashboard (unfortunately I'm unfamiliar with the 406).  You then need to check for live either side of the control unit/relay and then trace it back to the switch.  Unfortunately it's a case of tracking continuity until you lose the live.  Relays are fairly cheap to replace and you could even try it as a 'trial and error' just to see if it then works.  If its a dedicated control unit then it could be pricey.

If there is no live at the fusebox then it could be a trapped or damaged wire.  Again you need to trace it back.  Have a look for a wiring diagram on the net or see if there is a manual you can borrow from a library or friend.
