Download and read the RAVE, it also has exploded diagrams, plus troubleshooting:

OPERATION

The sunroof can be operated with the ignition switch
in position I or II. The sunroof can also be operated for
up to 45 seconds after the ignition is switched off
provided the driver’s door is not opened. When the
driver’s door is opened, a further 45 second period
commences. During the 45 second period the one
touch function is inoperative.
If a failure of the sunroof motor occurs for whatever
reason, the sunroof can be closed manually. Removal
of the interior courtesy lamp allows the fitment of a
special key into a slot in the motor drive. The sunroof
can then be manually driven to the closed position.
The motor contains a microswitch and a Hall effect
sensor. Two gears, driven by the motor at one end of
the pinion drive spindle, trip the microswitch every
thirteen revolutions of the spindle. When the
microswitch is tripped, an open circuit signal is sensed
by the Body electrical Control Module (BeCM). The
signal from the microswitch, combined with signals
received from the Hall effect sensor, are used by the
BeCM to calculate the exact position of the sunroof.
The Hall effect sensor is also responsible for the
operation of the anti-trap function.
Tilt Operation
With the sunroof panel closed, pushing the lower part
of the rocker switch operates the sunroof motor to ’tilt’
the rear of the sunroof upwards. The motor operates
for as long as the switch is operated until the glass is
tilted to its full extent. If the switch is released before
the full tilt position is reached, the sunroof panel stops
at the chosen position.
When the tilt function is requested, the cables pull the
guide forward, forcing the peg on each lever to move
in the slot which raises the sunroof panel to the tilt
position.
With the sunroof panel in the tilted position, pushing
the upper part of the rocker switch, operates the
sunroof motor to lower the sunroof panel. The motor
operates to lower the panel for as long as the switch is
operated until the panel is fully lowered. If the switch
is released before the fully lowered position is
reached, the sunroof panel stops at the chosen
position.
Open (slide) Operation
With the sunroof panel closed, pushing the upper part
of the rocker switch operates the sunroof motor to
lower the sunroof panel and retract it backwards. If the
switch is held, the motor operates until the switch is
released or the panel reaches its fully open position. If
the switch is pushed momentarily (less than 0.5
seconds), the panel will retract automatically to a half
open position. A second short push on the switch will
automatically retract the panel fully. When the panel
retracts, a wind deflector automatically raises at the
front of the sunroof aperture which serves to reduce
wind noise.
When the open function is requested, the cables pull
the guide in a rearward direction, forcing the peg on
the lever to move in the slot which lowers the rear of
the sunroof panel below the roof. As the panel begins
to move, the forward panel attachments slide down a
ramp in the guide, lowering the forward end of the
panel below the roof.
With the sunroof panel half or fully open, pushing the
lower part of the switch operates the motor to close
the sunroof panel. If the switch is held, the panel
closes until the switch is released or the panel
reaches its fully closed position. If the switch is
pushed momentarily (less than 0.5 seconds), the
panel will close automatically until it reaches the half
open position. A second short push on the switch will
automatically close the panel fully.
The sunroof has an ’anti-trap’ function which prevents
the sunroof panel from closing if an obstruction is
sensed. When an obstruction is sensed, the motor will
automatically retract the panel to the half or fully open
position. A message ’SUNROOF BLOCKED’ is
displayed on the message centre in the instrument
pack. When the obstruction is removed, the panel can
be closed by the normal method.
Battery Disconnection
If the battery has been disconnected, the one touch
and anti-trap function will become inoperative. These
functions can be reset by fully opening and closing,
then fully tilting and closing the sunroof panel in one
continuous operation. An audible warning will sound
and ’SUNROOF NOT SET’ will be displayed on the
message centre in the instrument pack when the
sunroof is being operated.
When the above procedure has been successfully
completed, an audible warning will sound and

’SUNROOF SET’ will be displayed on the message

There will be a allen head screw that you need to turn to close the sunroof, I do not know which way to turn it, but you can figure that out.
It will be by one of the corners if I remember right.

pull of the cover to the lite above your head and there is the motor, you need a special key or a screwdriver that fits it to wind it back.

Rovin, Thanks for that.... Going to try it to day

I did it ..... It worked great...reading Rave and how things work is one thing... but fixing things takes you guys... your the the Best...thanks

Buzz I need to thank you.. forsure cw

I know the thread is v old but I just wanted to register my gratitude at this solution which, as today I had just that issue of the sunroof not working on my P38, was absolutely invaluable. Many thanks!

Welcome to the board Alan. Quick suggestion.... go to the 'user cp' section of the site (which can be found at the top of the thread near the 'new reply' button) and edit your signature in order to put the year and model of your truck in there so that it is easier to know quickly what truck you have when you (inevitably) need help.

Thanks v much for the tip. Yes I will get there asap and load the data.

What fools we all are....!
