about HVAC good !!!

[Grenadian]

This is a review of the HAVC. I wrote a post a while ago that the HVAC was not working properly, but now that I look at it,
I think it didn't work as I thought because the weather wasn't cold at that time.
As a result, it literally works in "auto" mode is "auto".

Korea is now entering winter, and I'll tell you the results of observing the IG's movements in several stages.

<Status>
1. 7℃(20℉) or higher: Hot air does not come out at all toward the feet. About 80% of the back seat, 10% of the front face, and 10% of the bottom and left and right sides of the front window come out.

2. 7℃(20℉) or less: Hot air comes 100% toward the feet. The bottom of the front window, front face, front left and right sides, and back seats do not blow air,
but when the temperature reaches a certain level, they all start blowing out along with the feet.

3. The temperature and strength of the hot air gradually decrease.

4. As the indoor temperature drops to a low point, the same sequence is repeated. Above 1, 2 and 3.

5. It will work the same if you start engine in “Auto Mode” or HVAC OFF mode. Or, if you turn Auto Mode ON after the temperature has risen sufficiently, it will work the same.
** Tomorrow we will move to an area where temperatures are -4℉ (-20℃). I will add the results from there.
P.S
Coolant condition
1. High pressure side: Normal
2. Low pressure side: Slightly lower than MIN

Interesting, a more sensible post than "the Grenadier heating is completely useless".

I refilled around 700 ml into the (in driving direction right) system during the last three weeks. After the first refill the it took only an hour of heating to empty the reservoir again. Obviously the air that had been trapped in the system had been replaced by cooling fluid.
I topped another two times (every time less then the time before) now the heating works well. Tomorrow I start a longer trip north and will see how the heating will cope with Scandinavian weather.
As there are still some bubble sounds in the system from time to time I will take the cooling liquid with me so I can give the car a refill when needed. I will have a closer look how the system works in different outside temperatures.
