I am now convinvced that alot of our problems with air flow in the vents is due to the junction in the HVAC box. This thing is made of plastic . I took mine off I could not believe how poorly made it was for such an impotant piece. Two sets of vacuum lines junction there and I had one that was totally clogged and two that the junction holes were impaired because of the plastic holes ( the juction piece) being made poorly. I am going to soon start a thread with pictures to show you what I mean. Watch for it this week end.
