Heater Blower Control Slider

[Guest kristal17]

Hello folks,

 

Newbie here. Was wondering if I could possibly ask you chaps (and chapesses) for some help.

 

The heater blower control slider on my Xsara is only working on setting number 4.

 

Nothing is happening on setting 3, 2 or 1.

 

Do you reckon F16 needs changed or is it something more serious/complicated? :blink:

 

Any help or advice would be much appreciated.

 

Thanks in advance,

 

Kris
