Hi, apologies if I'm in the wrong area for this, seems like the place where people post bravo issues, my air power is very weak from the internal air vents (right arrow) whereas the up and down arrows airflow is good, I've read that it could be a very expensive fix via dash removal to replace the linkage but have seen that it can be manually opened via accessing the scuttle panel but the thread ended there, could anyone point me in the right direction for this or link me to a thread where this is located, am guessing this is a common issue so hopefully should be a quick fix, thanks in advance
