Sunroof wwill not not close opened slowly ,now won't close.Could it be fuse?-Heather

Ok, so the first poster obviously didnt read the question and just posted the first thing he googled.

So I'll try.
You have a short, most likely on the actual drive motor itself or in the switch. I wouldn't bother with replacing the fuse again until you take the motor out or test the switch for a short.

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 .

You mean GMC not Chevy ! Chevy doesn't make the Envoy . There is no way to manually close the sunroof !
Power Sunroof Inoperative
If voltage is not measured on the sunroof switch open signal or sunroof switch close signal circuits, the fault could be in the retained accessory power (RAP) supply voltage circuit, battery positive voltage circuit, or sunroof motor ground circuit. If the sunroof motor is not being powered, neither will the sunroof switch signal circuits.

Can be manually close with the good allen key. Take the plastic with lights off. Put it where the circle and turn slowly.

This is an electrical problem. Check fuses and replace if necessary.

Some sunroofs have a open switch like the drivers window. You push it and the window will open automaticly. The button on your sunroof could be jammed so even though you can close it as soon as you release it, it will auto open on it's own.

Hey Paul, there are limit switches integrated into the motor on your sunroof, usually if it stops completely its because it detected a restriction, such as leaves, or dirt, if there are no visual sign then with the key on hold the switch to the full open position for 10-12 sec then hold it in the close position for the same, cycle the key and see if it reset. The motor can fail as well but it's not very common.. Do u hear any clicking from the motor area when this occurs, also check all fuses to be safe as well,..

It can be faulty motor or loose wiring issue or faulty /weak sunroof controlling switch or there is some blockage for sunroof to come down to close or sunroof out of its track the headliner is out of its way.There re many possibilities.All this basics needs to be checked.For further troubleshooting,go through this help link:----

The fuse and relay box on the E30 and E36 models is located in the engine compartment. The E36 models also has relay boxes located under the left side of the dashboard.

Circuit Breakers
Resetting & Replacement
Circuit breakers are located inside the fuse panel. They are automatically reset when the problem corrects itself, is repaired, or the circuit cools down to allow operation again.

One of the less known about fuses that can cause all this to go out is the fuseable link. It is in a black plastic box near the battery. It is an appx 60A thin metal strip fuse. Check the website link to the right for more info.

Also, I suggest check your Fuse Diagram in the BMW 525i Owners Manual here.

Power Sunroof
Emergency Closure Operation
The sunroof is equipped with an emergency closure feature should the sunroof motor fail or the vehicle has lost electrical power. To close the sunroof under these conditions:

1. Remove the front headliner trim panel.
2. Using the 6mm hex key that is included with the tool kit, insert the key into the hex socket and turn the socket to close the sunroof.

Removal & Installation
E30 Models



Fig. Sunroof components-E30 3 Series shown, E36 similar




Fig. Sunroof lid retainer clip location-E30 3 Series shown, E36 similar

1. Open the sunroof lid 2-4 inches (5-10cm).
2. Unclip the roof liner frame and push back into the opening.
3. Close the sunroof lid and loosen the screws on each end of the gates.
4. Pull in the retainers, remove the center screws and lift off the lid.
5. Remove the cover over the motor and gearbox. Close the sunroof lid, if not already closed.
6. Disconnect the wiring harness and remove the 3 mounting screws. Remove the motor and gearbox.
7. Push the cables back evenly on both sides. Remove the rail covers and pull the cables out of the guides.
8. Place the cable in the center position of the gate and press off.

To install:

1. Install the cables to the gate. The cable are marked with the proper side of installation. Do not lubricate fabric covered cables.
2. Pull the cables through guides and align the cables. Insert a hex key through the gate and cable at the 0 position.
3. Install the motor and gearbox. The motor and gearbox must be synchronized with the hole in the drivegear aligned between the centers of the 2 gears. Torque the bolts to 2.0 ft. lbs. (2.8 Nm).
4. Install the sunroof lid. Use new screws and torque to 2.5 ft. lbs. (3.5 Nm).
5. Adjust the sunroof lid. Pull the roof liner frame into position and clip into place.

E36 Models

1. Close the sunroof fully. With a quick actuation of the sunroof opening button, open the sunroof so the back edge of the lid depresses 0.08-0.12 inches (2-3mm).
2. Slowly push the roof liner panel back into the roof. Do not force or use a quick motion or damage could occur.
3. Remove the mounting screws and pull the lid off at the rear side. Do not operate the sunroof with the panel removed.

To install:

1. Install the lid and check that the hooks and levers align. Install the screws with threadlocker or use new micro-encapsulated screws. Torque to 2.5 ft. lbs. (3.5 Nm).
2. Adjust the sunroof lid. Lower the rear of the lid by operating the motor. Pull the liner forward and clip into place.

Good luck.

The sunroof continues to open and close normally from front to back, but the vent stays open.
