Service of the sunroof or moonroof windguard requires initial motor operation for roof opening panel systems that needed any repair work involving sliding glass motors, power shade motors, roof opening panel glass, or roof opening panel assemblies or when new motors, glass units, or assemblies were installed. Inspection of the sunroof or moonroof windguard starts by positioning the front sliding glass panel to its fully open state. To detach the air deflector you should first remove three screws from its frame and then detach it from the roof opening panel. Upon finishing the installation of the air deflector just run through the removal process in reverse order followed by front sliding glass panel motor activation.
