How to service and repair the air duct on Ford F-150 Heritage?

The process to tackle air duct maintenance starts by unfastening the screws of the plenum chamber and A/C plenum demister adapter before you can separate them. Separate the demister nozzle together with duct by removing their screws. You should execute the reverse steps when installing these components. Service of floor duct starts by first removing the restraints control module and then proceeding with the removal of the RH instrument panel brace. Tear away the LH instrument panel lower nut and put the brace in place while undoing the floor duct through the removal of two screws that anchor it on both sides.
