All four windows and sunroof opened mysteriously...with a disabled fuse for the sunroof. How is this possible?

Asked by May 15, 2014 at 03:17 PM about the 2004 BMW 3 Series 325xi Sedan AWD

Question type: Maintenance & Repair

When I woke up and went to my car this morning- all four windows were completely down as well as my sunroof being opened all the way.  I wouldn't think twice about it BUT the fuse for the sunroof had been disabled a few months ago because it needs a new motor.  They were able to put the sunroof back in place and pulled the fuse so we wouldn't forget and try to open it/ get stuck off track again.  And of course it rained last night!  Both sets of keys were stored safe in the house.  How is this possible and any thoughts about rain damage clean up?

I had a Lexus that would do that if you pressed the unlock button on the key fob more than 5 times in a row, got to be more of a problem that help I quit using the fob altogether. So you might check your owners manual to se if your car has the same style of remote system. As far as clean up get a good shop vac and set it up for water and start vacuuming, get as much water as the vacuum can get, this will take some time. Once that is done with weather warming up you can park it inasunny place and just open 1window and let the heat work on drying it the rest of the way.

Disabling the fuse will not work have to completely unplug the motor. The key fob itself if you hold the unlock button that will roll all the windows down. also if you use the key in the door and turn it and hold it
