First double check the placement of the headlamp bulbs. Make sure that the bulbs are connected properly and that no wires have been detached. You might also want to check to fuse that leads to the headlights. If that fuse is blown, just replace it. Look in the engine bay, on the passenger side for the fuse panel. The inside cover should identify the fuse for the headlamps, etc. it could also be the high low beam switch . it is a combo switch with the turn signals. try to gently move the arm in a figure "8" and watch for the lights to blink off and on or between high and low beams. try this in the high and low beam position. if the do anything but stay on continually replace turn signal/beam switch. also consider the dash dimmer switch The headlight switch activates a relay in the fusebox. Look on the underside of the fusebox cover for a diagram showing where it is. First confirm the headlight fuse is OK. Then, have someone slowly turn the lights on and off while you gently press the relay with one finger. If you can't hear or feel the relay clicking on and off, you may have to replace it.
