Hi all can anyone help please. My aux heater runs in a purge mode(does not fire) everytime I do something electrical on the car, eg unlock doors turn radio on etc. In addition since this has been happening, it does not fire up when the ambient temps are low enough. Any ideas on the cause/solution ...
