You will need to access the wiring to the sun roof and check for shorted/damaged wiring that might be rubbing on sheet metal and causing a short circuit, if you find nothing then the sun roof motor may be the culprit.

Sunroof does not open. Fuse is ok and the shade operates normally.

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 .

The Vermeulen Hollandia tilt and slide sunroof on my 1996 Subaru Impreza has stuck open. We swapped the fuse for another one in the car and it closed. However, when we tried to open it again it stuck


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!!

Most likely the fuse is burned out. Check the cars manual to find the fuse for the sunroof and check if it looks blackened.------------------------------------------------------------------------------

I have a 2002 Bravada and the sunroof does not work. There are no sounds and the switch was replaced and all fuses are fen, where is the motor for the sunroof located?


The motor for the sunroof is located in the roof typically under the head liner and trim. One additional thing you could do before ripping everything apart would be to check the voltage at the sunroof, before replacing the motor. If you have power than chances are you need a new motor. If you dont have power than you may have over looked a fuse or relay.

Take care

Sun roof does not work. how do you fix it. ?


Hi,

  1. Open the fuse panel. Turn the knob on the fuse panel cover counterclockwise or push in on the release tabs on the fuse panel cover (depending on the year of your Toyota), and pull down on the fuse panel cover.
  2. Pull the fuse for the sunroof out of the fuse panel using the fuse pullers in the fuse panel. Use the diagram on the underside of the fuse panel cover if you are having trouble locating the fuse for the sunroof.
  3. Check the metal strip in the middle of the fuse. The strip should not be burned or damaged. If it is, replace it with a fuse of the same amperage.
  4. Check the recessed track of your sunroof. Clear away any debris that may be stuck in the sunroof's track. Use engine degreaser and a wire brush to clean the track of dirt. Then, wipe the track down with clean paper towels.
  5. Apply hard grease to the sunroof wheels and track so that the sunroof can move easily once again.
Best regards

My 05 honda accord sun roof wont open


Hi,

The sunroof on your Honda may not be operating correctly. The most common problems with Honda's sunroofs is the track. This is especially true of early 1990s Honda vehicles. However, many Hondas use a recessed track that easily collects and traps dirt and debris. When this happens, your sunroof may not close and seal properly. Another minor problem is a blown fuse on some model years of Honda vehicles. Before fixing anything, however, troubleshoot the problem.
  1. Open the fuse panel. Turn the knob on the fuse panel cover counterclockwise or push in on the release tabs on the fuse panel cover (depending on the year of your Honda), and pull down on the fuse panel cover.
  2. Pull the fuse for the sunroof out of the fuse panel using the fuse pullers in the fuse panel. Use the diagram on the underside of the fuse panel cover if you are having trouble locating the fuse for the sunroof.
  3. Check the metal strip in the middle of the fuse. The strip should not be burned or damaged. If it is, replace it with a fuse of the same amperage.
  4. Check the recessed track of your sunroof. Clear away any debris that may be stuck in the sunroof's track. Use engine degreaser and a wire brush to clean the track of dirt. Then, wipe the track down with clean paper towels.
  5. Apply hard grease to the sunroof wheels and track so that the sunroof can move easily once again.
Best regards.

Sun roof will not open or close


First check your fuse box, for any fuse blow, position 26 in the Passenger Fuse Box (Box C), then keep in mind that the power sunroof is controlled by a switch that selects the direction of travel of the sunroof. The switch changes the polarity of the voltage going to the sunroof motor. This changes the rotation of the motor, thereby changing the direction of sunroof travel.


REMOVAL & INSTALLATION
(see Figure 1)
  1. Open the sunroof to the ventilation position.
  2. Disconnect the battery ground cable.
  3. Push down the sunroof headlining with a finger. Unhook the retaining springs with a bent piece of wire.
  4. Pull down on the headlining sufficiently to pass beneath the gutter rail. At the same time, slide the sunroof to the rear to release the catches at the front.
Do not pull the sunroof too far to the rear; otherwise, it will be difficult to remove again.
  1. Unhook the spring retaining brackets.
  2. Remove the retaining screws from the sides and front.
  3. Remove the sunroof.
To install:
  1. Fit the sunroof into position and install the retaining screws.
  2. Install the spring retaining brackets.
  3. Slide the sunroof forward to engage the catches in the front.
  4. Install or reposition any trim moved for access.
  5. Connect the negative battery cable.

My sunroof is stuck open on my 1999 jeep grand cherokee laredo? Would it be a fuse? If so, how do you change it?


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 should illustrate 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.
