REPAIR SUNROOF ELECTRIC/MANUAL
Introduction
Twin sunroofs are fitted to the vehicle, the open/close
sequence for both electric and manual versions
sharing the same operation:-
A Closed position,
B Tilt position,
C Fully open position. When fully open the sunroof
slides back in a tilt position over the vehicle roof.
The electric front and rear sunroofs, operated by roof
mounted switches are controlled by an electronic
control unit. A roof mounted isolation switch is also
fitted to cut off power to the rear sunroof.
On manual sunroofs a pull down handle is used,
incorporating a depress button that locks the handle
after each sequence.
Twin sun blinds are installed in the clamping frame of
the sunroof and can be drawn forwards
independently.
