Re: Sunroof is stuck in open position. No movement when...
I have the same problem on my car and took it to the dealership to get it checked, they said that the 2001 is the one of the only years that doesn't have a manual close function. They told me my motor was completely dead and the only way to close it is to replace the motor. My only problem is knowing where the motor is. I would have yours checked if you haven't already.

When pushing close switch?
are any sounds from switch,
is any movement to window,
The fuse can be found in one of two places. Fuse box on driver side lower dash by driver door.
Relay Fuse Center, under the hood, upper driver corner.
A bad fuse would cause NO POWER to sunroof. IF window moves back and up, fuse is good. Cause for not closing, or moving forward would be wire connection to forward/close switch, or a bad switch. Also could be window track.
Checkand clean sliding track, window could be geting stuck on something.
Check wiring to switch, this means pulling the switch.
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 .
First, were the fuses that you replaced the first BLOWN sunroof fuse with the same size? Example, 5 or 10 or 20amps...I am going to assume they were the same or you probably would have burned up the sunroof motor or just blown the replacement fuse real quick. Can you help the motor by pressing the palm of one or both of your hands against the inside of the sunroof glass and push the sunroof button while trying to help the sunroof slide back with your hand or hands. (Obviously if you use both hands someone else will have to push the sunroof button unless you have an extra arm and hand) If it slides back with the help of your hands, either the sunroof is sticking against the slide or the motor is worn down and just doesn't have enough strength to move it anymore. You could try to use a light coating of oil on the slides where the sunroof touches as it slides back and forth. Something like WD-40 preferabley but you could even use any motor oil, worst case "Cooking Oil". Good luck with my suggestions!!
Definitely, you'll have to take a look to see if any obstruction is visible. To check the fuses first you'll need to find them. The fuse block cover shouldillustrate what each fuse is for. You can visibly check the fuses, with a flashlight. Just take a look at the sunroof fuse and check that its not burned. That the metal inside goes from one side to the other and its not burned or broken. You can use a test light or a multimeter, a test-light will do. I usually check them visibly, its obvious when you have a blown fuse just by looking at it. Its better just to pull out the suspected fuse to check it.
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
