The air flow from the vents seemed to have fixed itself, so that's good. Thursday morning I turned the heat dial to max and let it blow at max for about ten to twenty minutes and the heat finally kicked in. I tried replicating that this morning but the heat never did turn on after about ten to fifteen minutes of driving, maybe I needed to wait a bit longer, who knows. Not sure if this is common with SRIs or not but it seems to have effected my heating.The intake shouldn't have anything to do with the HVAC system, but I could be wrong. Sounds like maybe the HVAC splitter behind the dash has malfunctioned? I think there is a couple splitters back there, one that controls hot/cold air mix, and the other two would be for driver/passenger vent mix. Im sure others with more experience will chime in shortly.
