my heater/AC is working but it's not blowing as much air as it should. I've changed the cabin filter. the blower reacts to the speed control but there's just not as much air. Does anyone have any insight?
Well, I guess start simple. Have you checked the knob that sets which vents to use? If it's being split between the dash and foot well vents, it'd definitely have less pressure behind it. Might also be the blower starting to go out. I'm not sure how you'd check for that though.
