If the filter is not restricted and you have confirmed that you have full speed on your blower motor, I would check for any leaks within your ductwork but also see if there might be a problem with your blend door actuators not sealing properly to direct full airflow through your vents. There is also a possibility that some debris could've fallen into your vents causing the blend doors not to fully close. I would also check to see if there is any damage to the actuators and blend doors as well. Look for leaks within your vents and duct work as well. One other thing you want to check for is to see if your evaporator core is icing up causing it not to allow airflow to pass through. It is a pleasure to help anyway I can.
