Hello all,
Has anyone experienced the strange unpredictable heating motor/ Air conditioning pump, loud whirring noise that starts without notice when the engine is running. It would appear to be in or below the centre console area between the front and back seats if you know what I mean.
Do these cars have some sort of heat booster or space heater that anyone knows about? Any help will be welcome, I cannot figure out where the noise originates from or what it is supposed to be doing, ie it doesn't produce any extra heat and as I've already said is totally UNPREDICTABLE.
