The other day when I shut my truck off the airflow from defrost, vents and floor was fine. When I started it back up, it is extremely weak. AC is still cold and I can still change the airflow to all levels. Blower motor seems to sound ok. Air is just really weak

The first thing I would check is the blower motor squirel cage for debris also debris within the ac box that could clog up the evaporator core etc.

I found the problem. A filter had broke off of the housing above the blower motor and landed on the blower.I couldnt suck any air. I just broke it into smaller pieces and removed it from the blower motor home completely. I don't need it.I couldnt care less is there's a little dust blowing through the vents! Thanks for your help

Your welcome I figured the problem was somewhere around the blower motor.I would have suggested the cabin air filter but didnt see one listed for that truck.
