heater

I'm in my first six months, and first winter, with my 2007 FJ. Previously I had a 2003 Jeep Wrangler Sport, soft top. My Jeep could quickly heat up and be toasty, with the soft top and cold weather. I know it was a smaller vehicle than my FJ, but... I never really feel any warmth on my feet...

Does anyone know the AC/Heater blend door calibration procedures? I have a 2007 FJ. I was able to replace all of the actuators, but the air mix actuator is moving too far in either direction. Thank you in advance.
