I was in B-more yesterday on St Paul. Guy had a 70s-80s Datsun pretty much rotted out (bottom of doors and quarters), HE CHECKED THE PASSENGER DOOR TO SEE THAT IT WAS LOCKED! I was about ready to stop and say, you wish someone would steal it.
If the lighter doesn't work, probably the fuse. Should be under the dash, labeled in a little plastic box of fuses. Can get a replacement at any auto supply place for dirt. If the windows are manual, then you should be able to fudge them down, try pushing on the glass with your palm while trying to get the window down. Drove in a FIAT in Europe where you could open any of the windows by palming the glass.
