Electric cross arm window controls are installed
in all cars as of the 1980 model year. These new
window controls guarantee smoother door window
operation and in future will replace all parallel
arm window controls for Types 911 and 911 Turbo.
Later the Parts Catalog will be changed t o include
the mechanical cross arm window controls, which
replace the mechanical parallel arm window
controls after depletion of stocks and can be in-
stalled in all doors.
Service installation of these new cross arm window
controls will require exchange of the lift channels
on the door windows or use of new door windows.
