Most of the time on the Trailblazer it is the dimmer switch that goes not the Module. Try replacing the dimmer switch and i think it will take care of ya troubles.

SOURCE: i got a 2004 chevy

If it is anything like my 04 GMC Sierra, there is a relay panel under the hood. In that underhood box where you found the fuses, there are also relays. They pop out (the diagram is on the lid of the box). After the GMC hit 200k, the relays started going out. The high beams are on a relay, the lowbeams are on a different one. You can pop one out and replace it with the horn or foglight relay if you want to check it out. I am betting that the DRL bulb just happened to go at the same time. Mine go out regularly..I would say around every 10-15k miles. I don't know if this helps, it is just something that I have run across with a similar vehicle.

SOURCE: 2004 Chevy Impala lowbeam headlamp socket/connector burns--though bulb is fine. Replaced once already and now same socket has burned again--and the bulb is still okay. What gives?

Hi Miles, Have you replaced the head lamp bulbs and maybe used a higher output? That can overheat the fuses and or the connectors. The over heating and damage will usually be caused by loose connections causing high resistance and heating. Make sure the connections are tight. Regards John

Subaru outback wagon tail light not working off


There are several components of your 1997 Subaru Outback that can cause your tail lights to stop functioning correctly. To help pinpoint the cause of the problem, it would be very helpful to also check your front marker lights. If the marker lights are working, then we know that the problem is not the headlamp switch or the tail and illumination relay (located in the fuse and relay box).

The components to check are:

> Fuse #23 (20 Amp) in the Main Fuse Box.
> Fuse #5 (10 Amp) in the Fuse and Relay Box
> Tail And Illumination Relay
> Headlamp Switch

2003 GMC Envoy low beam head lights will not come on. The bulbs are not blown, fuse's ok, no power coming to the head light connector. minimal power to the fuse compartment with fuse removed. 9 to 10...


The problem is a Headlight module. Fuse box under the hood has two black modules side by side, the one on your right is the headlight module the one on the left is the fan module. Try swapping them, if the headlights work replace bad module, don't drive vehicle with the bad module in the fan slot. Mine kept going bad because I had a high intensity bulb on one side.

Lowbeam head lights dont't work after changing bulbs


{: ) For the lowbeam headlamps, check these fuses at the underhood fuseblock:
LO HEADLAMP LT 10amp
LO HEADLAMP RT 10amp
HDM 15amp (main power for the HDM relay. Important)
Voltage is always present at the HDM fuse. When you switch on lowbeams, voltage should be present on the LT and RT fuses. Otherwise check the HDM relay or swap it with another known good and similar relay.
Check the two fuses again for votage:
If voltage is now present, proceed with wiring checks, checking for open wiring going to the bulbs.
If voltage is still not present on the two left and right fuses, but the HDM fuse and relay voltages are okay, you may be having a bad fuseblock.

I have a 2002 GMC Denali and my low head lamps both went out at the same time, the high beams work and lows do not? Any ideas?


this strongly sounds like a body control module(bcm). everything is controlled through computer systems, this just happens to be one of the units that controls headlamp operation. prior to replacement of an expensive component, check your power distribution box under the hood on the drivers side. it is aslo possible to have a loose connection under the fuse or relay. check these items first. cheers

Low beam dosent work. bulb is good highbeam works cant find fuse for lights. its not underhood


Hi,
It has been because the lamp bulb or halogen lamp module has reached the end of its serviceable life, not because of any wiring problems. Low beam burns out first because it is on the most. If low beam is lost simultaneously in both headlights, I would check fuse first, then the headlight switch. If low beam is lost on one side only, it is almost always going to be due to the bulb or lamp module needing to be replaced. In that case, replace them in both headlights because the other one will be going kaput in short order, as well.
Most like the low beam filiment is bad but the high beam filiment is still good, try replacing bulb. If replacing bulb does not fix problem then you probably have voltage problems and should check the voltage reading and the plug.
OR
isolate the wire that comes from the headlight switch to the headlamp bulbs for low beam and check to see if there is a short in the wire. You can find this wire by using a test light turn on the key and get a good ground with the test light poke the wire and see if the test light illunimates with the headlight switch on.
check the wires, and check the fuse for your lowbeams. could of blown a fuse on your lows, but your highs will still work.

The fuse box is located in the engine compartment,on the driver's side. Has thumb-screw retained cover.
Thanks for contacting fixya.com
