i have a 99 accord v6 with 70k miles(2 days ago). and yesterday it started to make a strange noise. sounded sort of like a humming/vacuum type noise but its hard to really explain a sound. anyways, in addition to this noise there were several light on in the dash that shouldnt have been on. for instance, the seatbelt light, ebrake light, it said the doors were open, and the maintenence required light blinked for a few seconds then turned off. why is this happening? anyone have any clue?
