HVAC air flow problem

Post by strongt3310 »

I've got a 2001 SE with a low air flow problem coming out of any of the vents. Be it floor, vent, or defrost settings. The mode actuator is moving for the different settings. As is the actuator for the temp control. Cabin filter is new.

I do get slightly better airflow in the cold setting then in heat. The blower motor is working good but I just can't get any air flow. Any ideas ?

I was hoping it was something else. Funny if it is dirt. The old owner of the car had a cabin filter installed. Funny much dirty would get past it.
