AIRFLOW IN CAB WEAK

2005 Dodge Ram • V8 2WD Automatic • 93,000 miles

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.

The ac box is buried behind the dash your going to have to remove the blower motor see what you find and go from there.

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.
