Hello everyone
I am almost finished with my 2004 4.2 s type
Which I have had from New

So I do know the history of vehicle

I am now trying to sort out the heating fault codes
To try to get heater to work properly

As its getting cold in new Zealand
This mornings it was mins 7 dregrees Celsius
or 19 degrees Fahrenheit


I dont have a mongoose pro JLR OR
SDD PARTHFINDER
As to brings a set up like that into new Zealand is appropriate 2.5 k by the time i pay for shipping import duty and electronic taxes

I just have a cheap icarsoft cr pro Cost $ 600.00
symptoms are
Heat only from defrost vent won't change from that
Heat only in rear of vehicle

These are the codes I have got

B1262 DEFROST SERVO MOTOR CIRCUIT FAILURE
B1264 FOOT SERVO MOTOR CIRCUIT FAILURE
B2537 AUXILIARY HEATER NO START
B2426 PASSENGERS SOLAR RADIATION SENSOR CIRCUIT OPEN
B2796 DRIVER SOLAR RADIATION SENSOR CIRCUIT OPEN
This is what I have replaced
new radiator
New heater control valve from snd barratt uk
new interior heater control module from sng Barratt uk
Cabin filter
New water hoses including under intake manifold

ANY HELP WOULD BE GREATLY APPRECIATED
THANKING YOU

 

Not trying to bust your behind, but you have two open threads for the same general symptoms. Anytime anybody creates a new thread, any important details or responses in the original thread tends to get overlooked.

For example, have you played with the doors as described in post #4 here? This should help isolate how the door actuators are responding. In addition, the actuators may be fine but the linkage has come disconnected, hopefully an easy fix. We have not seen any response from you about the behavior of the actuators and doors:

Concerning the fault codes you listed above:

Auxiliary heaters were only installed on diesel models, so that is a nuisance code which means nothing.

The solar radiation sensor basically fine tunes the temperature output from side to side. A bad sensor isn't going to kill heat completely. At worst, it might throw things off a few degrees.

 

The b1262 will never go away. Jlr program fault as i have learned
