Having problems with your 2003 Chevrolet TrailBlazer ?
2003 trailblazer low beam headlights go out
\015 2003 trailblazer low beam headlights randomly go out. Sometimes they come back on immediately and sometimes not so quickly.\015
Check your dimmer switch on your steering column. Your plug may be loose or not getting a good connection. Your dimmer switch may be going bad as well. The same thing happened on my 1994 Chevy, but the lights never came back on, on mine. I found that the dimmer switch had gone bad. If this is the case, I recommend buying one from your local chevy dealer and spending the extra money. I went through two that I bought through napa before buying a OEM replacement because the napa ones just didn't last.
