Jaguar XF air vent Problem
Hello my name is Kurt. And life in spain. I will thank everyone that can help me. And im happy to be here in this forum. So i want to explain my problem, and sorry my english is not perfekt. My car is a Jaguar XF 2.7d and my problem is with the ventilation. They don't work like they need. Sometimes they works perfect but very less so like every 2-3 months is working everyting but only for 2-3 hours. and then is the problem the 4 ventilations are open all the time, i can change the temperature on the display but the air temperature is not chaning. i can change it on the display where i want that come the air. But the air come only on the feet. Can somebody help me what that can be?
thanks a lot for your help

Does it only circulate air over your feet no matter what setting you select on the display?
For example, if you turn off "auto" climate control, select the front vents and turn the fan on full, does it still just come through the lower vents by your feet?
With regards to the temperature, are you trying to heat or cool the air?
Have you tried reading any error codes from the OBDII interface?
I'm going to try this in Spanish too (or rather I'm going to see if I can word it sensibly so that google translate can make sense of it)

¿Solo circula aire sobre sus pies sin importar la configuración que seleccione en la pantalla?
Por ejemplo, si apaga el control de clima "automático", selecciona los respiraderos delanteros y enciende el ventilador por completo, ¿sigue entrando por los respiraderos inferiores a sus pies?
Con respecto a la temperatura, ¿estás tratando de calentar o enfriar el aire?
¿Has intentado leer algún código de error de la interfaz OBDII?

The "registers" are the air vents.
You seem to have a fault to the registers and the air distribution. I'd check the power in to the control unit is ok (LIN_POWER_2), the GND and the signal distribution to the air vents. It might be you have two faults, both with the vents and the air distribution motor.
Failing that it could be a faulty module but that seems odd if you can control the fans.

And now is working other Time nothing.

The could still be an electrical problem, from the wiring diagram is seems that both the instrument cluster and the climate control system use the same ground, behind the instrument cluster on the right hand side of the "IP beam". Perhaps there's some damage to the loom or the grounding connections, or just a bad connection somewhere in there. Unplug it all and clean the contacts/connections?

witch one is the Electric heater control modul?
i have check all the cabels and find nothing.

Neither. You want to disconnect the auxiliary electric heater. On my 2009 XF 3.0 diesel, at the heater, a small green/white wire goes to it. Disconnect that. Your wiring may be a different colour. If this works, go to your garage & get them to program it out too.
I downloaded both the files above but couldn't open them & I can't find a decent diagram for you as I'm doing this on my phone. The S-type had a diesel powered Webasto auxiliary heater. With the XF range they changed to an electric one. It's purpose is to help heat up the coolant quicker in cold weather, so the engine & heating warms up quicker. Do a Google search for 'Jaguar XF auxiliary electric heater' or ask your garage. Mine was easy to get to, but I have a different model.
