Ok i just bought a 92' 328i and when i first got it when the key was out of the ignition and car was off power windows were off (everythings good) now im not sure maybe i hit a button or something but when the ignition is off and key is out i can still use my power windows and sun roof... did i hit a button or is this a wiring issue??? like i said it didnt do it when i first purchased it 3 weeks ago...

^^ mine does that, if i turn of the vehicle and take out the key, but dont open the door(s) the vehicle gives me about 20 secs of power to windows/sunroof. Only after you open a door or outside of the 20 sec window all power to sunroof and windows are gone.

i would be ok with that... but it doesnt stop after 20 sec... i will come to my car in the morning and open the door and be able to put the windows down right away with out starting or putting the key in the ignition

all i can think of is a fused window relay or regulator, check them out.

check all your wiring maybe the previous owner crossed wires with some stuff? never really know when buying a used car
