Did you check fuses 24 27 and 33 for power and continuity? All for the wipers.
If ok turn the key on (not running) headlights on, wipers on, turn signal on and measure the voltage from the negative post of the battery to the ground stud under the dash near the steering wheel shaft and/or in the left kick panel.
I would not want to see more then a few tenths of a volt.
Check fuses 20 and 21 for power for the low beams. Power with the key and lights on.
Pull the head light switch out, power to pin 1
Do the dash lights come on?
