Aux heater problem

[Jake F]

I have a 2008 Cali. Recently I cannot get the heater to fire up without running the engine. I have charged the battery for 24 hrs to be sure - everything else working fine..any ideas?

The automatic go-to for any T5 heater problem!! It's certainly what needs fixing on ours...

Does it work on hook-up? Does it start up at all?

Not sure about Earth Shunt - I will first find out what that is an next I will check it!!
The heater fires up fine on hook-up or with the engine running.
Thanks very much for your reply!!!

If it works fine when hooked up, it sounds like it is the earth shunt.
Another clue is if the internal lights and the control panel display start
to flicker whilst the heater is firing up.
