    got a 08 silverado and noticed that when heat/as turned to the off position with fresh air selected still blowes pretty good, and varies with speed of truck, speed up blowes faster slow down blowes slower is this normal. when turned to inside mode it will stop when turned to off position. any help

    This sounds normal. When it's in fresh air mode, this is your flow through ventilation w or wo the fan. As long as the air flow stops when you have it on inside mode & shut the fan off, this is correct.
