have you got means of a obd2 and CANZE - it should tell you how much 'bar' pressure the refrigerant gas is .. - you may have a leak and there might be no gas left in the system, and no gas will just blow out cold air out the vents.Hi, no warm air or aircon cold air so need to check fuse for aircon compressor but not sure where it is located - any help appreciated.
In a zoe the aircon/heatpump does not run on 400v DC does it? - even the cabin additional heating runs on LV (12v?) electrical PTC 1800w when it only calls for it (talking about Zoes in mild weather countries, maybe it different for cold countries)If I remember the aircon runs from 400V and there is a special fuse in one of the control boxes on the 'engine', best not to meddle with it!
blowing 'slightly warm air' could suggest that the PTC electrical addtional cabin heaters are kicking in - they are around 1800w (1.8kw) of power so that will give you some heat out of the ventsA bit more information on the 'no heat problem'
Car is 2016 and is R motor. When the car is stood as if Idling it does blow slightly warm air up to the windscreen(no fan noises from engine bay) but when travelling it just goes cold. There are no DTC's showing except occasionally I get a 'Inverter fan assembly' fault but this does not bring up any MIL lights and will clear straight away. I have attached the screen shot from CanZe showing the data from climate control, which I think shows gas pressure is ok but the compressor RPM is 0 so assuming this is not working - so how can you test if the compressor is working - assuming this gives heat to the cabin View attachment 141500
Who pressurised it? Normally you see 20 or so BAR when the compressor is running. But its 50Bar with compressor at zero rpm. Seems way to high to me. Over pressured?I have had it re-gassed and it is showing 51 bar as my attachment shows on my earlier post from a screen snapshot yesterday. I have tried the hair dryer trick twice but will have another go today just to make sure.
But what I do not understand is why I do not get any clues from what is wrong from either snap- on diagnostics or CanZe - surely some data must be able to point to where the problem is.
My comment was based on my experience when owning a Zoe. Never saw over 20-ish BAR when under compression in use. It would be under 10 when idle, which is what this screen grab was showing. Zero compressor RPM, so 50bar seems very high.Depends where the sensor is I think. On an ICE car, the pressure can appear high on the LP side when the A/C is off, it then comes down to normal when the compressor runs.
