No rear heating.

I’ve just discovered there is no heat coming out of the rear vents behind the centre console, any pointers as to where the air pipes connect to the heater?

Hi

Oh blimey mate , just what u don’t need after resolving the other issues

Plus found the recalibration just in case it’s needed

Automatic Calibration: The ATC module will automatically initiate a calibration routine every 175 hours of vehicle life. This occurs approximately 1 minute after the ignition has been switched off once 175 hours is reached. In this instance, the programmed de-frost LED will not blink.


Forced Calibration: The ATC module can be manually forced to carry out a calibration routine on the stepper motors. This can be carried out by holding down the ECON and recirculation buttons on the ATC module panel while simultaneously switching the ignition on. The ATC module will now carry out a calibration routine on the stepper motors, but will flash the ECON LED rather than the programmed de-frost LED.

Hope this is useful to u

Yes that’s a great help thanks, I never realised there was ducting under the seats to the rear, I’ll check if anything is coming out of them, I haven’t had any complaints from rear passengers and I never sit in the back so it’s no big deal, just that I like to keep everything working as it should.

It maybe that face vents aren’t meant to be hot ? See if the front ones are hot

Your reply has solved the situation, the amount of air coming out of the rear centre vents is minimal when the system is set to normal(auto, all vents open) which I was checking it on, but as you suggest if I set the air to face vents and put the fan on high I do get air in the rear centre vents, so it seems everything is ok as there is also air coming from under the seats to the rear when set on normal that I wasn’t aware of. Thumbs Up
