2004 Chevy Trailblazer Low Beam Headlights
Re: 2004 Chevy Trailblazer Low Beam Headlights
Ok, switching around the HDM relay should NOT cause any problems. You must have done something wrong, popped other fuses, or fried a module somewhere. But, back to the headlamp problem, you should remove the bulbs and check the connectors (sockets) for any burned terminals. That is a common issue as well. If it's not that, you're in the same boat as the other guy here and either have a wiring issue, bad headlamp switch, etc. Any of that would take some involved checking and diagnosis.
