Cooling fan is designed to come on only when A/C, defrost, or engine temperature exceeds 235 degrees
Fan should come on when the A/C is turned on. Fan should also come on around 1mm before redline or at the very edge of redline as per the gauge on the cluster.
Neither should go in your air conditioner! I assume you mean the radiator which has coolant, but this is not an air conditioner and will not make your air in the car blow cold. If you need coolant for the coolant system then the type of coolant depends on the make and model of the car. However, it is ALL anti-freeze. That is what DEX cool is, but Dex cool is for specific engines. In general, most engines that I have come across will take DEX. What type of car and what year is it?

Cooling fan should come on when coolant temperature exceeds 235 degrees Fahrenheit or A/C or defroster are turned on

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.
