Hi, wonder if anyone can shed some light on this as my local dealer is not sure and doesn't want to start taking apart the dashboard unnecessarily. I've noticed in the winter months on longer journeys when the engine is up at higher temperature the climate controlled heating just gives up blowing and I start to feel a draft, etc.. In the summer months the same applies to cooling and the blower just stops delivering the cold air to keep the cabin at setpoint. When it does this I generally note that cold air is still delivered to the rear passenger vent in the back of the armrest but nothing from the front vents. Putting on AC max results in a lot of noise from inside the dash over to the left around the glove compartment. However, turning off AC immediately starts to release more air through the front vents and then, after a few minutes of restored air, turning the AC back on starts to chill the air again, though not as chilled as when starting the car from fresh. Is this the AC compressor at fault, blower motor, blend valve(s) or perhaps even some sensors somewhere? The only fault code the dealer has managed to extract from the ECU related to icing up on the AC compressor? I have had the refrigerant recharged recently which the AC service agent said wasn't significantly low on gas.
