Need help on how to fix my headlights on 2001 Chev Blazer. When I move the steering wheel up and down some times the headlights go out and then come on. In certain positions they do not work at all. Tonight coming home from work they did not come on at all even when I tried various positions of the steering wheel. Any ideas?

Yes, check for a shorted wire in the steering column.

If you are not mechanically inclined, get this fixed at a shop ASAP so you don't kill yourself at night or even another driver.
