Heater barely blowing out of vents
Posted: January 20th, 2013, 1:07 pm
I am wondering if there is a common solution to a common problem with my heater.
Even with the fan on HIGH, barely any air blows out of the vents.
-All positions work
-No difference whether it is on FRESH or RECIRC
-The fan itself blows like crazy with the fan box to heater box pipe removed
-Fan box to heater box pipe is not plugged
-I can see the HOT/COLD flap moving through the inlet hole to the heater box
-No difference whether it is on HOT or COLD, so the problem isn't likely a plugged heater core
Basically, the blower fan blows a ton of air, but there is a restriction somewhere in the heater box.
I am out of ideas. Is there some sort of filter [that could be plugged] in the heater box that I am unaware of?
Thanks in advance!
