Not familiar with the vehicle, but a generic answer could be a bad relay (assuming they used one) or a bad high-low beam switch. Good luck
The headlights are on two different fuses. The high beams are on one fuse and the low beams are on another fuse. The fuse for the low beams may need to be changed.

Often it can actually be a faulty turn signal!! As silly as this sounds it is quite common. First thing to do is clean the contacts on the turn signal, if you still get high beams and no low beams you probably need to replace the turn signal switch.
You didn't mention if you checked/tested the low beam headlamps or not.
Check your fuses by your left foot in the driver's seat. There is a panel with a bunch of fuses and it could be simply a burnt out fuse!
A blown fuse can affect just your high beam headlights. The high beam and low beam headlights are on separate fuses. The separate fuses ensure that you will not lose all of your license at the same time.
CHECK FUSABLE LINKS AND THE IGNITION SWITCH.FOR 12VOLT REF
Check all fuses and check for burn out headlights, high and low beams
have you checked your fuses? it could be as simple as that This is true, there is a separate fuse for the high beams, low beams and radio. Fuses for 1999 LHS are located behind a side panel (drivers side) of the dash next to the steering column. Driver's side door must be open and there is a wiring diagram on this panel.
There is a detachable plastic piece below the coin tray marked "Fuse." If you remove that there should be a clear plastic insert that diagrams the fuses. If yours is missing, the low beam fuses are in the middle row, the two far right fuses. The low beams are on the row with three spare fuses, fourth and fifth from the left. They are all 10A fuses.
Possibly the multifunction switch (switch in columm). Check the bulbs, fuses etc first
It sounds like the low beam/high beam switch is bad. Fuses are not the problem since they are built into the headlight switch and would cause headlights to blink or not come on for both high and low beam headlights.
