This morning driving our son to school, the heat/fan would not go on - could not defrost windows. When my husband hit a bump - everything bumped on. This also happened with the headlights a few weeks ago - I was driving at night going 55 mph on the road and all the lights inside/outside the car turned off (thank goodness I had the fog lights to turn on). I did not test the brights. Then a couple of miles later down the road, the lights came back on.

Any ideas as to the problem? Estimated cost to fix?

check body ground from battery for corrosion or loose. also clean battery terminal ends. check ground at back of lh headlight and at base of dash left of steering column. If it still continues have it scanned.
