The heater blows good heat but not a lot of air thru vents.

What is your question?

When you turn the setting up to another number to blow more hot air out it stays the same. I hear it go thru all the settings but doesn't go any faster. Could there be a heater door stuck or something wrong with the actuator?

Yes, there could be a door stuck "but", if the blower is not going faster, you could be having an issue with the blower motor resistor. Just depends if yours is manual or automatic. http://www.autozone.com/cooling-heating-and-climate-control/blower-motor-resistor/isuzu/ascender-2wd/2008/6-cylinders-s-4-2l-mfi-dohc?filterByKeyWord=blower+resistor&fromString=search
