When I turn on either the heater or air conditioner in my truck I get almost no airflow out of the vents. The flow is slightly less than the flow used to be on the systems lowest setting but I can feel some flow. The cabin air fliter is not clogged and I wasn't sure if this meant it was the blower motor or if it could possibly be a defective switch or sensor. Also before tearing into the truck how do I know if my blower motor is tab or bolt mounted as I have seen both listed for the truck

You need to first access the motor to see if it is getting power. Chances are you have a bad relay or resister if there is no power to the motor. IF there is power, replace the motor.
