SEITZ WINDOW IDENTIFICATION CODE
Please look for the AG??????????? number bonded between the the 2 panes in the top RH corner of the window viewed from the outside of the vehicle.
Please note S4 and S5 windows both say S5 in the code, but the glazing panels are all the same. The only difference between S4 and S5 is that S4 windows have a roller blind fitted and an S5 window has a concertina pleated blind. Often ( but not in all cases) S4 windows have very dark brown, nearly black handles and S5 and S6 tend to have grey handles.
