Have '01 v70. Sunroof opened all the way, now won't close. I've pulled the light assembly/cover to get a look at it. The black plastic electronic box seems to have some sort of sensing ability to it that allows it to close, as there is a small gear that rides on the sunroof motor cable. I at least need to get the sunroof closed. Are there instructions on line somewhere that offer explanation? Do you have advice? Please help. Cheers!

check fuse and relay if good than possible motor ot track problem their should be a mechanical bypass that will let you close it if stuck open the following information is courtesy of monte carlo forum

To check the condition of your original sunroof guides:

1. Gl*** in closed position.
2. Locate & remove 3 torx bolts on each side of sunroof glass. Lift glass out of sunroof opening & set aside in a safe place.
3. Locate "J" shaped cover plate at front of sunroof track assembly. Remove 2 torx bolts from each cover plate.
4. Lift up bracket to remove.
5. Inspect the plastic guides on each side. The sunroof cables attach to guides on front outer corner. Inspect this area closely for damage.
6. Do not operate the sunroof with the J plates removed.

Troubleshooting:

If the sunroof guides are not broken & the glass is a uniform height along the rear edge your problem may be a stripped gear inside the motor. The motor has a manual override:

1. Get access to the motor by removing the map light/switch console or lowering the front of the headliner.
2. Insert a large standard screwdriver into the nylon bushing at the center of the motor hub. Push up & turn the screwdriver to manually move the sunroof glass. If the unit will fully open & close manually, you most likely only need a replacement motor.

If your sunroof is stuck in the open position follow these steps to get it closed:

1. Remove the glass.
2. Try to close the unit without the glass. Many times one side will still be operational and close correctly.
3. Try to slide the inoperable lift arm forward. If it moves, slide it forward until it stops.
4. You now need to slide the original plastic guide forward to lower the arm to the closed position. Using a standard screwdriver, push it forward. The lift arm should begin to lower.
5. If the lift arm will still not fully lower, remove the J plate as explained above, sometimes the sunroof cable will need to be lifted up to allow the guide to fully slide forward.
6. Reinstall glass.

There should be a crank on your fuse box cover {hexagonal section}. That is the manual closer for sunroof. You have to take off cover for readong/interior light to access the cranking point.

depending on the vehicle you may be looking at a bad sunroof motor, or the regulator(roof track and cables) could be bad, on some cars you can replace these things seperately, and on some you have to replace it all as one assembly. In most cases if you pull your headliner down so that you can see the motor there will be a manual opperation "port" usually a 1/4 or 3/8 drive ratchet opening so that you can manually close the roof until you get it fixed. In most sunroof motors I've seen the manual opperation port is either a red plastic circle with the ratchet drive opening in the middle, or there is a round plastic insert that you have to pull out to access the ratchet opening. hopefully this helps, if not try updating the question to include year make and model of the vehicle. Good luck!

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:----

These limits are not adjustable.

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.

Not familiar with the Volvo, but many cars (Toyota, Lexus, Acura, Honda, etc.) have drain holes at the corners of the sun roof assembly. These holes allow water that gets past the sunroof gasket to drain through tubes that carry the water to the bottom of the car, where it exits the car.

These drain holes are prone to clogging. If the Volvo setup is like those cars mentioned, you can see the front drain holes by opening the sunroof and looking closely at the two front corners of the assembly that holds the sunroof. I have used plastic weedeater line to open up these lines. Compressed air can also be used.

fuse block is located behind the panel on the right side of the center console, at the bottom. Pull the panel off and the fuse is a 15A located just above a large black relay. Color is blue, and the fuse is not near another fuse.

Be sure to pull the bezel around the map light and check the connections on the switch and motor. they may be corroded.

Also the tracks tend to break very easily.

I had a similar issue and started to notice other electrical failures along with the gas gauge. My rear doors would not lock and my rear wiper stopped working. I started pulling fuses and relays to see if this would reset, no go. But then I hit the jackjpot. In the rear electrical panel, below all the fuses and relays is a 2" x 2" black plastic square with a big screw in it.

Remove the screw and pull evenly on the black square. This seems to be a major electrical hub for the car. I reconnected and all 3 of my issues disappeared...I read somewhere that a fix might be to disconnect the battery for a few minutes, which I guess re-sets some relays and circuits, but I guess this did the same thing. Good luck.

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.
