double check your fuses, there is one for each side hi & lo, (total of 4) swap fuses if everything still checks out then take a good look close at your headlight connector and see if it looks like anything is out of whack, then test the back of harness with a meter and see if there is power going into harness if no power at back of harness trace it back from there.
