It's somewhat cold. It's just very little cold air coming out. Can't hear the vent blow the air as well.
your blower motor is stuck on low
Coming out of the vents around 43 degrees
Cold air return vents are the ones on the wall
The air is off.
I don't know it's a new furnace and the outside unit was checked. everything runs good except that the air is not coming out of the vents cold it's barely cold.
to keep the plant cold
The heater may not be on - but the fan still blows air through the vents when they're open !
no
Vacuum hose that runs over the thermostat housing is leaking at that location.
The a/c - heater controller is out...........
The air should be comming out of the defroster vents. If so, most likely, it is the vacuum line that controls the vents. It is on top of the engine below the air cleaner, and runs to the front right of the engine. Buy the replacment so you know what your are looking for.
the middle vents only supply air from the ac unit using a separate in dash fan. the floor and defrost vents come only from the heater
