Question about 2003 Chevrolet TrailBlazer

1 Answer

I have a 2003 Chevy Trailblazer. The headlights (both L & R) all of a sudden quit working. No DRL as well. High Beams work fine. Is this a fuse or relay issue? Looked on fuse box diagram, but found two separate fuses for low beam L and R...obviously can't be both at once. Any suggestions? Thanks

DRL lights won't come on. The only lights that come on automatically are the park lights. I replaced the DRL module and that didn't help. The park lights come on when I cover the light sensor. Do you have...


I probably should not be answering this as I'm no expert, but ...
Let's see now, DRL comes on when in gear and headlights off, emergency break off.
Silly question but, are headlights working manually (click on manually and verify both working)? High beams, low beams OK?
Check the fuse. The DRL fuse in the underhood fuse box and the label tells you which one. I think it's 31 or 32 but not sure.
Aftermarket lamps (esp the stupid blue lamps) can cause this if a higher wattage is used. (Burns the plastic lamp sockets).
Also check the DRL relay.

Low beams not working but high beams are on a 2000 chevy metro


The headlight relay provides power to the dimmer relay, then power goes thru a fuse for each light for each circuit (4). The low beam fuses are in fuse block 2. The dimmer relay is controlled by the daytime running light module. The headlight and dimmer switches send signals to the DRL module. You may need a shop manual to troubleshoot the circuits.

2005 trailblazer headlights go off ocasionally


the click you are talking about is the high beam relay.
you nedd to get a tester or voltmeter and check the sockets for 12v.
there has been instances where both low beam bulbs went at once.
do the daytime running lights work?
if not,supect the daytime module...it is also wired into the parking brake.
if you put the park brake on first,then start the vehicle,the dtr do not come on

Both Headlights Work On Lowbeam But Not On Highbeam.


First identify if your day running lights (DRL) are working. The DRL and high beams will work on the same relay. If your DRL are working, but not your high beams, you may need to replace your high beam relay which is found in the fuse panel under the hood of the engine at the right back corner; near the firewall, and passenger tire strut mount. If there is also a problem with your DRL with the high beams, its likely the DRL relay which can be found tucked under the dash.

There's usually a cover that says "relays", "fuses", etc. Lift the cover and look underneath, it should label the relays. If not, consult a manual or repair book. Try swapping similar relays from know working accessories if you don't have a new one handy.
