i,am assuming they are power windows. if none of them work then check the fuse. did you try all the switches or just the ones on the drivers side? i,am thinking it might be the switch.
they were working all day until a couple of minutes ago i went to go roll them up b/c it looked like it was going to rain and all 3 of them don't work. WHY? its a honda crv 01. how much is it going to cost?
