My knowledge are not very hight on cars. But I like to troubleshoot before I leave the care to garage. The car is a Peugeot 807 2.0 HDi, 2004 modell. This summer on a long trip I received a "cooling level" notice. I filled in more antifreeze. After a short time, I received the same message. The temperature was above 90 degrees. The radiator fan is not starting when car engine I warm. I noticed that also the AC stopped working. I have been looking for troubleshooting procedures on youtube for "fan not starting", but find very little on this car. I have checked the fuses. Im glad for all advise for what and where to troubleshoot?
