I went through the summer without fixing it as a lack of heating wasn't an issue! Lived with it until Christmas, but then it seemed to get worse. Freezing cold air delivered from dashtop and windscreen vents only tempered by switching to 23 degree manual heat from dash vents.

As the cabin temperature sensor in the centre console is an easy change, I decided to do this first. Not sure it was the problem, but a 2nd hand part from eBay was only £10, so nothing to lose (FoMoCo part 6G9N-19C734-AB used on lots of Volvos, Fords and Land Rovers).

I had a small rattle/buzzing from the bottom of the centre console, so decided to fix this at the same time.

When changing the temp sensor, I noticed the original part had a rattle when shaken, which was not there on the replacement. Could this be my mystery noise?

Anyway, temp sensor changed and reassembled and the rattle has gone. Test of the CC and all is working as expected. CC now set at a sensible self-regulating 20 and very comfortable.

Original fault code also disapeared from VIDA: - CEM-B10EA14 - Positive Temperature Coefficient heater - General Electrical

Fantastic result!! Thanks to all that helped.

Hi

Just found your post about electric heater issues
CEM-B10EA14 - Positive Temperature Coefficient heater - General Electrical

I wish to ask if you come across similar fault

B10EA13 - Positive Temperature Coefficient heater - General Electrical fault. OPEN CIRCUIT ??

I have stripped my s80, checked all wires and so on, all fuses ( unless I missed any ).
Got volts on main power connectors and so on.

All look perfect.

Would you be able to speculate ??

Hi,

I have had the same fault codes and I believe symptoms, the drop below freezing seems to really trigger it. Was wondering if you could tell me the location of the sensor?

Thanks
