Sunroof Description and Operation (One Connector System)
This diagnostic procedure is to be used for the 1 connector Sunroof System that combines the sunroof control module with the sunroof motor/actuator.
The Sunroof System consists of the following components:
• BATT MAIN 2 Fuse 50 A
• Body control module (BCM)
• RAP relay
• S/Roof Fuse 20 A
• Sunroof module (includes sunroof motor/actuator)
• Sunroof switch
The Sunroof System is controlled by the sunroof switch and the sunroof motor/actuator assembly.
When the ignition is turned to RUN or ACCESSORY, or when the retained accessory power (RAP) system is active, the body control module (BCM) applies a ground to the RAP relay in the instrument panel (I/P) fuse block. This activates the RAP relay and allows battery positive voltage to be applied through the SUNROOF Fuse to the sunroof module. Ground for the sunroof module is supplied from G302.
The sunroof can be placed in 3 preset positions:
When the sunroof switch is placed in the OPEN position, a ground is applied from the sunroof switch low reference circuit , through the sunroof switch and to the sunroof switch open signal circuit. The sunroof motor/actuator then applies voltage to the sunroof motor open control circuit and applies a ground to the sunroof motor close circuit. The sunroof motor then opens the sunroof to the full open position.
When the sunroof switch is placed in the VENT position, a ground is applied from the sunroof switch low reference circuit , through the sunroof switch and to the sunroof switch open signal circuit. The sunroof module then applies voltage to the sunroof motor open control circuit and applies a ground to the sunroof motor close circuit. The sunroof motor then opens the sunroof to the VENT position.
When the sunroof switch is placed and held in the CLOSED position, a ground is applied from the sunroof switch low reference circuit , through the sunroof switch and to the sunroof switch close signal circuit. The sunroof module then applies voltage to the sunroof motor close control circuit and applies a ground to the sunroof motor open circuit. The sunroof motor then closes the sunroof.
The sunroof can be placed in any preferred open position when:
• The sunroof is in the fully opened position by pressing and holding the sunroof switch in the CLOSE position until the panel has reached the desired position then release the CLOSE switch in order to stop the sunroof
• The sunroof is opening, it can be stopped by momentarily pressing either side of the switch.
The sunroof control module, sun roof actuator, and the sunroof motor are integral parts of the sunroof module assembly and are not service separately.
Your best bet , take it to a qualified repair shop or buick dealer .
Can you give a check to the micro switch that is connected to your boot lock?
If the catch gets stuck, open your drivers door, leave it open,reach across & press down the lock on the passenger front side. The locks will lock/ unlock themselves, because they sense a door is open. Repeat this action until you hear the boot unlock. Also, keep your battery well-charged.
Let us know if this helps!!
03 Jeep Liberty sunroof wont close. I have 4 sunroof buttons; Open, Close, Vent and ASC. Open and Vent buttons are working fine. Close button is not responding. ASC button is flashing red and green but does nothing when pushed. I have no way to get it closed
you can open and close you sunroof "manually" remove the plastic cover next to your sunroof and dome light buttons (above your rearview mirror) there is an allen wrench stored inside... insert the wrench into the corresponding hole and you can close or open you sunroof by turning the wrench
hi sounds like a faulty sunroof relay keeping the motor running it may well have blown the fuse or burned the motor out if you connected it back up and it doesn,t work at all but should be able to turn the sunroof back manually look on the sunroof motor there should be sometthing like a slot for a large screwdriver or a bolt head of sorts just wind it back and then check the relays and fuses if your switch is a electronic one make a make shift one and try [simple switch]on and off as this is delicate circiutery and the slightest short can destroy it best of luck yates210456
