Steps to Resolve:
  1. Inspect and remove airway obstructions: Check around all fans and air intake areas in your van. Carefully remove any items you find obstructing the fans or air intakes. Ensure that these areas are clear to allow free movement of air.
  2. Check for Error Resolution: After clearing the airways, observe the TRUMA panel. The blinking error should cease if the obstruction was successfully removed, restoring normal operation.
