Disconnected Battery, Now Sunroof Won’t Open

Sunroof Won't Open

Sunroof stuck closed –  fix stuck sunroof

MVS Forums Contributor brandonbeach14 disconnected his 2001 V70’s battery, and now his sunroof won’t open. This is how to fix a stuck sunroof after you’ve disconnected the battery, and explanation why it happens.

My electric sunroof won’t open after I had to disconnect the battery cables in the engine bay to get to the O2 Sensor connection below. It was disconnected for about 45 minutes. I have already pulled the fuses and the other int. accessory fuses, but they look good. I went ahead and changed the fuse just incase and still nothing. Is there an internal fuse in the motor? Or possibly the car has to run through a few drive cycles before everything comes back online?

This happens to me every time I do a battery. SO I will tell you all how to get it to work.

  1. Roll down drivers window and close door.
  2. lock car and wait 1 Minute (this will set the alarm system even if siren is bad).
  3. Reach in through open window and open door (will set off alarm).
  4. Use key in door to shut off alarm.
  5. Sunroof works. Have been doing this for several years and works every time.

Try disconnecting again the battery black cable (-) for 12h overnight. WHen disconnecting and reconnecting it have the ignition key in position II.
