I have a 2015 Ford Edge Titanium and it's loaded. Most conversations and on YouTube I'm finding is mostly earlier model edges and if it a Titanium after 2015 very little knowledge of any replacement parts or problem resolutions. Has anyone ever had to replace the blend actuator or actuators on the HVAC? This ride has 4 actuators 2 on each side and addressed as (A) and (B) actuators- one of each on both sides. I guessing that's due to having the dual option. Note: many suggest removing the panel at your knees under steering wheel for access but mine has an airbag there. Any help will be appreciated.
