Default S80 Sun roof won't open

2000 S80 sun roof won't open.After disconnecting the batteryto clear codes and resetting the locks, I still can't get the sun roof to work. Both sun roof fuses are good. Center overhead lights work and the two red seat belt and symbol on the mirrow light up so there is power there. I have locked and unlocked the car serval times using both the driver and passenger lock switches and the key.Key fobs were lost years ago by my kids. OBTW the car sat for three months during engine repairs without the battery hooked up and I last opened the sun roof in the fall. Moving the switch gets no reaction from the sun roof or any sound like a motor or relay is attempting to engage. I can push the sun roof up a little bit so it is not stuck to the seal. Any suggestions to get the sun roof to work are appreciated. Thanks, George

PS: Car now purrs like a kitten after I finally finished the valve job that caused the car to sit for a while....yipee!

Hi,

My sun roof is doing exactly the same thing and when I lock my car I get the message "alarm service required" upon unlocking (2000 S80). Now what exactly did you do to fix this? You will have to speak in layman's terms as I am not real car savvy.

The alarm siren will have to be replaced.
The siren is kind of a computer. When it goes bad it messes with the other computers.

S80 2000 is Certainly classy, composed. It looks a bit bland from the side views, and I *still* don't like the tail light design! Nothing great about the nose either, but not bad. Interior: Very nice. Excellent ergonomics, buttons, etc. It is obvious they tried to copy BMW in the way the lines are curved around the dash across the entire front panel, including the center console, but hey, trust me, that is NOT a bad thing! Works very well, regardless of originality (not a difficult thing for a Volvo to pull off eh? At least, not in past years). Very comforting colors (been in black, grey, and tan interior color combos), typical of a Scandinavian touch. Not terribly sexy, mind you, but pleasantly inviting cuz at the very least, your eyes will be comforted (but not excited). Overall, very nice textures everywhere.

As strange as it sounds, removing the Alarm fuse started my sunroof to work again!!! Cool and thank you people!

Default Unbelievable about sun roof

I just want to say thanks to whomever discovered that pulling the Alarm siren fuse would cause the sunroof to begin working. And they used to say the electrical system on Jags were screwy.

Thanks again

I am currently experiencing the same issue. I have tried the three consecutive lock/ unlock method, manually with the key and with the key fob; neither method worked. Additionally, I tried the placing the ignition key in position two, then holding the driver’s side window control switches that control the front drivers/passenger windows in the “windows up positions” for 8-10 seconds to resetting the UEM. Lastly, I have tried replacing both the Sunroof and Alarm Siren fuses; still no luck on getting the sunroof to work. P.S I tried the leaving the window down and reaching inside and unlocking the door. I set off the alarm w/o the siren sounding. Looks like I need to replace the Siren
