The roof opening panel is an electronically operated panel that can be opened or closed by pressing a switch located on the overhead console. It also has one-touch open, one-touch close, one-touch vent open and one-touch vent close features.
Roof Opening Panel
The roof opening panel assembly uses an integrated motor and module to operate the roof opening panel. The roof opening panel motor and module are installed new as an assembly. The roof opening panel is an electronically operated glass panel that can be opened, closed or tilted by the roof opening panel switch. Actuating the switch in either a forward or rearward motion supplies a ground to the roof opening panel motor/module. The roof opening panel has one-touch open and one-touch close features that are activated when the switch is momentarily pressed to the double detent OPEN or CLOSE position. These functions are controlled by the roof opening panel motor/module.
The roof opening panel motor must be initialized whenever the roof opening panel motor has been removed from the roof opening panel system, the roof opening panel assembly has been removed from the vehicle, a new roof opening panel motor has been installed or a new roof opening panel assembly has been installed.
Sunroof Description and Operation (One Connector System)
Sunroof
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:
• Open
• Vent
• Closed
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 .
To manually closed you remove the panel that houses the sunroof button and you'll see the motor which has a hex hole in the center that you can turn clockwise direction with a hex socket, to close it.
as a florida resident for over 30 yrs and a mechanic I'm Not a big fan of sunroofs I'm a convertible man. a sunroof can be a real problem and costly to repair. may I suggest pulling the fuse and not using the this feature as they are prone to leaking. this situation sounds dangerous and should be off line until a solution is found.
take a multimeter and check that your getting power to the switch and from it to the actuator when pressed. also check fuses and wires for bad/loose ground or short/bare wires
Push and hold the moonroof switch toward 2 . Once the moonroof has reached the full tilt position, release the switch. Push and hold the switch toward the 2 position again.
first the easy problem is the blower. it has a faulty resistor. it works on 4 because 4 bypasses the resistor to give you full power.
the sunroof sounds like you've got a shorted wire somewhere. the open power wire has to be shorted to a 12v power sorce. there should be a sunroof fuse. check the owners manual for it's location. but if the wire is shorted it may open without it. you may have to remove the headliner to unplug the sunroof motor itself.
I think I know the answer....your gear has slipped on the cable a few teeth. Set the roof to the desired closed position, flush with your roof. Then open the panel above the mirror by first prying off the switch plate and removing the two 10mm bolts holding the mirror. Remove the sunroof motor gear, or rather just lower it out so it is disengaged with the cables. Now connect the switch and hit the auto open button as if you wanted to open the roof with single flick of the switch. Now hit the auto close button (same button of course, but the single touch method). The motor will advance and stop to where it thinks the roof should be, closed, which it is. Reassemble the gear into the slot, test it if all good, replace the mirror and panel.
Good luck.

It sounds like it just needs to be reinitialized. Turn your key to the on position with motor off and hold the up/full vent button down for at least 30 seconds or until your sunroof either clicks or goes to the full vent position. That should fix your problem.
what do u mean "global open feature"?
the 2006 towncar is not equipped with the global open feature as in later models where you can press and hold the remote Unlock button and all windows and sunroof will open.
I dont think its possible for the sunroof to go full open by itself. Im actuallt unable to verify complaint
