Having problems with your 2002 Chevrolet TrailBlazer ?

Headlights turn off at night on their own. High beams work but not the basic headlights. It only occurs at night.

Answers :

There are two relays under the hood in your power distribution box one for low beam and one for high beam . Look under the box lid and see which one is which and replace it .. if you have to refer to your manuel in glove box to figure which relay is which. The box under the hood is like 3 inches by 8 inches and black in color .. hope this helps Jerry
