2005 Trailblazer Head lights
The headlights on my Trailblazer just stopped working. I've replaced all of the lamps and checked the fuses. I'm puzzled.

Probably need to track down the headlight relay; it may be dead.

Oh, yeah, can't run that much juice without a relay; the headlights are a big power draw.

And here's a twist from the good old days. Some cars had a built in circuit breaker IN the light switch. This was back in the day when the light switch was a pull/push knob in the instrument panel. If it tripped, you reset it by pushing the knob in (off) and then pulling back out to regain lights.
