Yep, I already did that, it helped, but overall I would say the airflow through my dash vents is weak. I even tested the blower motor for strength, blows just as strong as a brand new replacement, so that's not the problem. I also checked the recirc door, no blockages and performs perfectly. I am convinced that something in the HVAC box is just not opening all the way. Ugh, driving me freaking nuts!
