Good morning everyone!
It was hot in summer, the climate control worked properly and there were no issues. The temperature dropped to plus 12 in Anapa, and I wanted some warmth inside the car but found none. To be precise, it's absent when idling or driving slowly. The steering wheel heats up as well as my back and bottom, yet cold air is blown.
I started researching the issue. Logic suggests there’s not enough coolant in the system, but physics shows that the coolant level in the reservoir is normal ((((
So, I looked into this on forums, including foreign ones, and found out that it's not just my problem... This is a constructive feature ))) The level is fine, but there isn't much coolant.
Alright, clear all the plastic from the front and unscrew the air intake to access the reservoir.
