Check the thermostat. Make sure the fan switch is on auto. If it is disconnect the green wire from the control box at the air handler. This will disconnect the fan from the thermostat. If the fan continues to run, you have a stuck fan relay. If the fan shuts off, you have a bad thermostat.

An air conditioner evaporator is the part of the a/c system that the heat in your car transfers to causing cool air to blow from your vents. The blower is in front of it and it sucks air from the inside of your car and across the evaporator then blows out your vents.

To fix the air conditioning on the Peugeot 406, the steps will vary depending on the problem. Often, if the air conditioner does not come on at all, a fuse or wiring will need to be replaced. If the air conditioner blows hot air, the condenser or the coolant system might need to be replaced. If the air conditioner lacks a fan, the blower motor might be bad.
check fuse / relay if both are good you may need a blower motor
