AC question
Hi,
have three questions to place
1- on Automatic mode and willing to cool down temp the fan speed never reaches top speed, i.e. the last spot on the LCD never gets full dark. It's summer here and even if I set LO temp it never reaches top speed. If manually set the top speed is reached and last spot turns black; normal?
2- when cooling on Automatic mode the refreshed air comes only from center, never from leg room air nozzle or windshield one; normal?
3- when directing flow manually to windshield and or legroom, some air still comes through the central nozzles, is it ok?
Thanks for help
david

1. It's been my experience that AUTO mode doesn't use extreme fan speeds either high or low, no matter what the temperature. If there are 8 total available fan speeds, it chooses from speeds 2-7. As long as the fan speed reacts to temperature and you can otherwise manually adjust the fan speed, I don't think there's anything wrong.
2. Cold air should come from the center vents and the side vents. Windshield and floor vents are normally for the defroster and heater, respectively. You can manually change the distribution, although I'm not sure why you'd want to.
3. Yes.
