To Slide Open 

The slide open function will work when the sunroof window is in the closed or partially open position. To slide 
open the power sunroof, press and hold the sunroof switch rearward. This will apply an input to the sunroof 
actuator motor from the sunroof switch open contacts through the sunroof switch open signal circuit. The 
constant input, allows the sunroof actuator motor to control the opening of the sunroof window. From the closed 
position the sunroof window will lower slightly, then slide open, rearward, with the sunroof sunshade between 
the roof and the headliner, stopping at the comfort stop position. 

From the comfort stop position, an open request will slide the sunroof window approximately (1 in) 2.54 cm 
further open. The next open request will slide the sunroof window completely to the full open position. 

To Close 

To close the power sunroof from the: 

z

Open position - press and hold the sunroof switch forward. This will apply an input to the sunroof 
actuator motor from the sunroof switch close contacts through the sunroof switch close signal circuit. The 
sunroof switch close input at the sunroof actuator motor needs to be constant, switch pressed, allowing 
the sunroof actuator motor to control the motor to drive the sunroof window forward, until it reaches the 
closed position. To close the sunshade, this will have to be manually slid closed.  

z

Vent position - press and hold the sunroof switch rearward. This will apply an input to the sunroof 
actuator motor from the sunroof switch open contacts through the sunroof switch circuit. The sunroof 
switch open input to the sunroof actuator motor needs to be constant, switch pressed, to allow the motor 
to tilt the sunroof window down to the fully closed position.  

To Vent Open 

To open the power sunroof to the vent position from the closed position, press and hold the sunroof switch 
forward. This will apply an input to the sunroof actuator motor from the sunroof switch close contacts through 
the sunroof switch close signal circuit. The sunroof switch close input to the sunroof actuator motor needs be 
constant, switch pressed, to allow the sunroof actuator motor to control the motor to tilt the rear of the sunroof 
window upward to the vent position. 

Limit Switches 

The limit switches are within the sunroof actuator motor and supply data. The multiple data combinations allow 
the sunroof actuator motor to track the position of the sunroof window. 

Sunroof Actuator Motor 

The sunroof actuator motor contains the logic and is serviceable as one unit.
