Light switch at the bottom of the steering column may need adjusting.
Loosen the hardware at either end of the switch and select high beams, move the switch until h/beams come on, then tighten hardware.
Test selecting low/high beams to make sure the switch works.
With the other problems you've listed in other posts, I suggest you get a Haynes manual for the year/model of car to use a valuable reference guide. Better than nothing at all.
