Honda Accord 2008 moonroof problem need advice
Hey everyone i'm new to the forum but i'd just like to say that after browsing a bit im really happy to have found this place, I really didnt want my first post to be maintenance related but here goes nothing >___< well a few days ago I set my moonroof to the vent position and it opened fine, but when I pressed the button again to retract it into the closed position, it wouldnt retract! I can hear a *click* noise whenever I press the button again, not sure if thats a relay or something but besides that nothing happens, I know certain other models have a manual way to close the roof but i'm not sure if mine does, I've checked the rails and nothing is stuck in them, I really would like some help before having to take it in to a dealer :/ thanks for reading!

Re: Honda Accord 2008 moonroof problem need advice
Could be that the motor is burnt out too. Its not uncommon for the seals do dry out and become sticky after a number of years, forcing the motor to have to work much harder and it gets burnt out eventually.
Im not aware of a way to close it manually, so I cant help you there. |
Re: Honda Accord 2008 moonroof problem need advice
Try this to try to close it all the way. This isn't a fix; but, to try to close it for now.
To close: 1. Insert the key in the driver’s door lock. 2. Turn the key counterclockwise, then release it. 3. Turn the key counterclockwise again, and hold it. All four windows and the moonroof start to close. To stop the windows and the moonroof, release the key. 4. To close the windows and the moonroof further, turn and hold the key again (within 10 seconds of step 2). If the windows and the moonroof stop before the desired position, repeat steps 2 and 3. |
Re: Honda Accord 2008 moonroof problem need advice
This may or may not help to fix the issue. Try resetting the moonroof control unit.
1. Close driver’s door, leave it closed during the whole procedure. 2. Turn ignition to LOCK (0). 3. Press and hold the tilt switch, and turn ignition to ON (II). 4. Release the tilt switch, and turn ignition to LOCK (0). 5. Repeat steps 3 and 4 four times. 6. Check if the AUTO OPEN and AUTO CLOSE function still work. If they still work, the AUTO functions have not been cleared, go back to step 1. If AUTO functions have been cleared, go to step 7. 7. Press and hold the moonroof open switch for at least 3 additional seconds after the moonroof is fully opened. 8. Press and hold the moonroof close switch for at least 3 additional seconds after the moonrood is fully closed (tilted). 9. Confirm that the moonroof control unit is reset by using the moonroof AUTO OPEN and AUTO CLOSE function. |

Did you ever resolve this? If so, what was the fix? Having similar issues and I tried all these suggestions with no success.

Re: Honda Accord 2008 moonroof problem need advice
This same situation happened to my wife's 2008 on Saturday and we feared a $1000+ repair bill pulling headliners and messing with side curtain air bags but the 9 step RESET process was a God send and worked awesome.

But now it's stuck again and will not reset as before. Any 411 would be greatly appreciated. |
Re: Honda Accord 2008 moonroof problem need advice
I had read many previous posts & blogs, and then decided to do the wotk myself... Yet, because I was "visiting" my dealer on other mechanical business, i had them tell me the costs to " just close the moonroof":( it has like others here, ceased operating, and was stuck open(tilt).
Well, i didn't take up the dealer on the very pricey 'two hour minimum', instead this morning, I took down the rear portion of the Headliner, INSERTED A 4MM ALLEN WRENCH IN THE SOCKET PROVIDED ON THE LOWER SURFACE ON THE HALFMOON-SECTION OF THE MOTOR ASSEMBLY, WHICH I HAD NEVER HEARD MENTION OF(!), and closed the Headliner, reinstalled the rear courtesy lamp, and two passenger roof grab-bars, in about 33minutes.While i was there, I removed, opened, and affirmed that all that motor would ever do was "click". Professionally, i thought the elctronics for the hall effect driver of the motor, had failed. Now, I propose a simpler method: A flashlight in my proposed action to follow,to get your bearings up under the headliner, is advised. Now, I know that anyone can do this From the Front Seat if you are cool with operating in close spaces, and are gentle not to fold, or crinkle the headliner: From the rear of the moonroof, GENTLY Pull the Center of the Headliner down[its attached with a magnet center, and two velcro pieces out to the sides], about six inches, and feel around with the short end of the allen wrench(close space!) to the curved-section on the motor assembly; there's only one hole in the near center of the body of the device, the other spot closer to an edge, is a phillips removal screw. INSERT the allen wrench, //Now, you need an assistant, to look-see the movement of the Moonroof!...from above the car//.... As you turn the allen wrench in half-turns from your position in the font seat, the roof window will Move Thru It's FULL rotation...OPEN_AND_TILT. Choose the center of this 1 1/2 turns of movement to seal the window Shut.(as affirmed by your assistant), Then remove either the Electrical Connection to the motor-assembly, Or the Fuse under the dash, to prevent any accidental operation. Close the headliner, and think of all those bucks saved! Very glad to have found this soution, and provide it to others. |
Re: Honda Accord 2008 moonroof problem need advice
Moonroof stuck open in popup position. When I tried to close it I got a clicking sound. Performed the reset procedure given by tech8 and it worked the second time I did it. The roof is now closed.
Thank you for the advice. |

My was stuck on tilted up (clicking sound) and had to do the reset process over like 3 times for it to go down. I'm content for that as I can't afford to go to a dealership currently. Looks like this summer windows down only! Thanks Tech8 ! |

Re: Honda Accord 2008 moonroof problem need advice
I have a 2008 Honda Accord Coupe EX-L. The reset procedure did not work for me (the moonroof wouldn't move at all). The fix ended up being pretty simple for the coupe. You are able to sit in the back seat, and pull down on the headliner. There are only two snaps (one above the left back seat and one above the right back seat). You do not need any tools to pull down the edge of the headliner safely from this particular edge. With a 4mm allen wrench, closing the moonroof manually was simple. A couple of pictures may make this more clear.
https://cimg3.ibsrv.net/gimg/honda-t...79f4cfe7a3.jpg The allen wrench opening is visible and under the black portion of the motor (right side of the vehicle). https://cimg1.ibsrv.net/gimg/honda-t...713cfe1d67.jpg The green snaps are located over the left and right side back seats, and you can just pull down near them to get them to release. |
Re: Honda Accord 2008 moonroof problem need advice
This is the only way that actually worked with me! It took me sometime to find that 4mm hex, but a mobile phone camera made it easier However, while opening the roof liner, I teared the black plastic piece that sticks to the floor and attaches to the green connector, does anyone have any recommendation for a glue to stick the black plastic piece to the liner again ?
And once again man, this saved me much anxiety and money of course. |

Re: Honda Accord 2008 moonroof problem need advice
Hello Honda-Tech.com. tech8 moonroof control unit reset process resolves moonroof being stuck in open position. Moonroof Control Unit lost its reset settings after a few days of no moonroof use. I'd like to replace control unit for new and control switch. Where is the control unit located? Thanks in advance for any responses.

Re: Honda Accord 2008 moonroof problem need advice
4mm method worked perfectly. I've had this issue for 3 years now in my honda accord. Luckily it would just start working again. And I have a garage. But today. It was not working. I also did the 9 step process and nothing. Just a double click. Which eventually became just a single click. I was able to reach back far enough to put the 4 mm Allen wrench in the motor and shut it.

Re: Honda Accord 2008 moonroof problem need advice
This thread was an immense help in solving my moonroof issues so I decided to create an account and contribute some additional information.
I had the same issue as most of the posters with the moonroof being stuck in the tilt position. I followed the 9 step guide that user tech8 posted near the beginning of the thread in post 4. I would do steps 1-5, leave the ignition in the ON (II) position and then fiddle with the close button about 10-20 times. Then I would repeat this entire process about 10 more times until eventually the moonroof came out of the Tilt position, and moved all the way to the end of the open position. Then, standing on the car door sill, using a paper towel and small flat head screwdriver (you want a small one to get into grooves) I cleaned the entire channel that the moonroof travels on back and forth and through the tilt position. The problem for me ended up being debris caught in the channel, and once I cleaned this channel and the tilt channel, my moonroof started operation like new. After cleaning, I regreased it using white lithium grease. I've included images to show you the channels and areas you need to clean and regrease. Just a note that the photos are entirely out of order. The channel that you have to get from the inside of the car you can only get to when the moonroof is in the CLOSED position. https://cimg1.ibsrv.net/gimg/honda-t...03ad1254fa.jpg Clean the channel of old grease and debris on both sides using a paper towel and flat head screwdriver, then spray with White Lithium Grease. https://cimg1.ibsrv.net/gimg/honda-t...a82bcef04c.jpg This black piece is the tilt mechanism channel, make sure it clean of old grease and debris and spray with white lithium grease. https://cimg9.ibsrv.net/gimg/honda-t...c5ae828dc3.jpg This is the entire channel. You can see where I sprayed the white lithium grease as this is where the moon roof travels. Clean the entirety of this channel end to end of debris and old grease. The very small flathead screwdriver is an absolute necessity as there are grooves in this channel where the debris gets lodged. After cleaning, spray this channel with white lithium grease. |

Thanks for all the help to the forum, the members . I much appreciate it. Navi |
