Easy way to force Head Lights to turn On for Chevy Trailblazer 2002.

Chevy vehicles are known to have headlight problems where they won't come on. This is an easy way to force the low beam head lights to come on so that you can get where you are going, without having to use your brights, and blind people on your way. Sometimes the cause is the electronic relay, and some times it's the control module under the back seat.
