Repeat this process to replicate the "clonk" noise and (using a flash light to look through the front bumper grilles) visually check the operation of the upper and lower active grille air shutters to confirm which active vane is being obstructed.

   Does the upper active grille appear to be being obstructed?

   Yes  : If the upper  active grille appears to be obstructed GO to F2.

   No  : If the lower  active grille appears to be obstructed GO to  F3.
