DESCRIPTION AND OPERATION
POWER SUNROOF
Power for the tilt and slide switches is supplied on
circuit F10. This circuit is HOT in the ACCESSORY
and RUN position only, and protected by a 20 amp
fuse located in the fuse block, cavity 14.
Power for the fuse is supplied by circuit A31. This
circuit connects from the ignition switch to the fuse
block.
Feed for the A31 circuit is supplied on circuit A1.
This circuit is protected by a 30 amp fuse located in
the Power Distribution Center (PDC).
SUNROOF OPEN/CLOSE
When the operator selects sunroof OPEN the
switch connects the feed circuit F10 to circuit Q41.
The Q41 circuit connects from the switch to the
OPEN side of the motor.
Ground for the motor is supplied on circuit Q42
from the motor back to the CLOSE side of the open/
close switch. The ground is passed through the bus
bar in the switch to circuit Q45. Circuit Q45 connects
from the open/close switch to the tilt switch.
The ground is passed through the switch to circuit
Z8 and finally to ground.
When the operator selects the CLOSE function,
power and ground are reversed.
TILT OPEN/CLOSE
When the operator selects tilt OPEN circuit F10 is
connected to circuit Q43. Circuit Q43 connects from
the switch to the CLOSED vent limit switch in the
sunroof module.
The voltage is passed through the switch to circuit
Q46. The Q46 circuit connects from the limit switch
to the slide switch OPEN side.
Power is passed through the switch to the Q41 cir-
cuit, then to the power sunroof motor.
Ground is provided on circuit Q42 from the motor
to the slide switch CLOSE side. The ground is passed
through the bus bar in the switch to circuit Q45. The
Q45 circuit connects from the slide switch to the tilt
switch CLOSE side.
Ground is passed through the switch to the Z8 cir-
cuit and to ground.
When the operator selects the VENT CLOSE func-
tion, power and ground are reversed.
