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


Do you know how to do automotive electrical testing ?????? How to read a wiring diagrams ???? http://www.bbbind.com/free_tsb.html .Videos on youtube Ohms Law Tech Tip from L1 with Dave Hobbs Copy of Voltage Drop Essentials TST Motor Age The only way to find the problem , testing !

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 .

Sunroof won't close automatically.


Is the motor receiving power? If not you have to check electrical system to locate the place that is not transmitting power. Could be a fuse/relay, switch, bad connection.

If the motor is turning and nothing happens then the drive mechanism from motor to sunroof is stripped. Not good.

Cant open sunroof


Look for a blown fuse in the fuse box first. If the fuse is not blown, locate the power roof relay, and, while operating the power roof switch, have someone listen for a clicking sound coming from the relay. If there is a clicking sound from the relay when you activate the switch, look for a stuck roof latch, and, if there is no click, try replacing the roof relay.

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

2003 mitsubishi outlander sunroof will not close.


Hi

could be a few things, firstly the fuse for the sunroof, secondly some have a small relay next to the motor near the sunroof. if the switch for the sunroof is on the roof pop it out of the trim or unscre it if it is fixed with screws, check the wiring looks right if still wont close then simply unplug the wires off the back of the switch, tel me how many wires you have and the colours, you can attach 2 toghether and this will close the sunroof if the switch is the part that has failed, Always check fuses first!

If your stuck still get back to me for more info

My sunroof has opened and now it won't close. Any clues?


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
