I've been observing the following for the past few days. I'm driving quite a bit at 12 in the afternoon these days. In some days I travel alone and have both the AC vents facing towards me, I keep the fan at speed 1 and find the cooling adequate. In some others days, my friend joins me, I place one of the vents to face him, now even if I place the fan at speed 2, I find the cooling quite inadequate. - The pollen filter and AC vents were cleaned in the recent service couple months back. - I never drive with windows open. - My car wears pitch black good quality tints The summer has just begun in Chennai. The temperature is hovering around 37degrees in the afternoons and it will go up to 40-44 in the next 2-3 months. Just want to know whether your car's AC unit efficient enough to cool the cabin in afternoons? What's your fan settings, sun films, city, etc?
