Heater not working, just 37 degrees output.

Post by Icon » 06 Nov 2015, 11:00

Hi.

I´v got a Citroen C5 2002 that i´m fixing for a friend.
The aircon heater only outputs 37 degrees celcius accordning to autocom at full heat.
It´s an dual aircon, and it´s the same temperature on both ducts.
I´ve been trying to look inside at the flaps but they doesn´t look broken.
All 3 flapmotors are working, no faulty axels.
The heater matrix have been removed and properly flushed, reinstalled and bleed.

Is there a rod controlled flap before the heater matrix thats connected to the other flaps that can be faulty?

All help is welcomed!

Is the water temperature gauge reading correctly, if not I would suspect the thermostat.

Something else to consider is the external temperature sensor. How hot does the C5 think the outside is? If it is faulty, the aircon will be mis-informed and weird temperatures will result.

Yep that's true, had it myself. Is the external temperature reading correctly?
