As French vehicle electrical specialists we are constantly conducting repairs on Citroen, Peugeot and Renault vehicles. Recently we had a Peugeot 407 in the workshop with a heater fault. When the blower was switched on it would only blow hot air. Now sometimes with vehicle electrical repairs things are not always what they seem. The customer of this vehicle was convinced that they had an electrical fault.
We conducted a computer diagnostic on the air conditioning unit but found no fault information. The next step is to start manually fault finding by going through the various components and circuits that are associated with the fault symptoms. This job turned out to be a mechanical fault with the temperature control flap that required the entire dashboard to be removed in order to repair.
Once the uprated parts were installed the heating system performed as normal.
