Question about 1999 Chevrolet Tahoe

1 Answer

Daytime running lights no longer come on

We have searched and searched and cannot find how or why they no longer come on. Is there some secret fuse for just the running lights or some secret we don't know (we are not the original owner)? Everything works fine when you turn the headlights on, but the daytime lights just quit.

    Yep, checked both - even a mechanic friend took a look and could not figure out why.

Have you Checked BOTH Fuse Boxes? There is one in the Cab and one Under the Hood on the Drivers Side.

    Ok, Try this. Under the drivers side dash on the right of the steering column is a shiny finned metal box with a wire going in and a wire coming out. This is the voltage reducer for the DRLs. Disconnect the wire coming out and the lights won't work.

Where is the fuse located for the daytime running lights on a 2005 Chev Siveraado?


It is located in the underhood fuse/relay box , marked DRL 10 amp fuse ! Also if that is good check the DRL relay in the same fuse/relay box .Your light sensor could also be bad .
The daytime running lamps (DRL) will operate when the ignition switch is in the RUN position, for automatic transmissions (A/T), the gear selector is not in the PARK position, the headlamp switch is in the AUTO position, and for manual transmissions (M/T), the park brake is released. When these conditions have been met and the ambient light sensor indicates daytime conditions, the DRL will illuminate. The ambient light sensor is a light sensitive transistor that varies its voltage signal to the body control module (BCM) in response to changes to the outside (ambient) light level. When the BCM receives this signal it will either turn on the DRL or the headlamps for auto headlamp operation. Any function or condition that turns on the headlights will cancel the daytime running lamps operation. The DRL can be manually turned OFF by depressing the AHL/DRL switch in the headlamp switch
Do you know that on inside of fuse box lid it shows what fuse is what .

Running headlights not working need solution or is there a switch for lights


Head light have two relays.one for daytime and one for normal night. the daytime switching the light to serial circuit and if one bulb is out down both Leigh quit working. Inspect your light high and low beam for normal operation . Inspect your fuses . Swap the daytime relay with identical one.and under the dash is module for daytime running light. inspect the red/black wire for ground from light switch and light blue/ yellow for power from 15A ECU-B fuse

My running lights are not working is there a fuse box inside the car


You have 3 fuses you need to inspect. All are under the hood in the power distribution relay box. Fuse first is the head main relay its a 30 amp fuse inspect to make sure its not open.You will also have a right hand lamp fuse and a left hand lamp fuse. Inspect and make sure they are not open. If all the fuse are good and your daytime running light are still non operation you can narrow it down to the daytime running light module. If this module sees a parking brake switch engage the daytime light will not operate.

My daytime running lights wont come on


The Daytime Running Lamps module is bad or check underhood fuse block for blown fuse.

Are the daytime running lights on this vehicle the amber ones or white ones? Are they the headlamps or the driving lamps below?

Where is the Daytime driving Lamp relay located


follow the wires to the drl relay. It must be inline from the regular light switch to the headlamps. I have a 1990 Cadillac Deville that has an aftermarket module that controls the daytime running lamps, and it is mounted on the driver's side wheel well.

Some relays are found in the fuse box under the hood.

If your daytime running lamps burnt out, take it to an electrical shop and ask them to check it out.

If you buy an aftermarket daytime running lamp kit, they can install it for you.

But, I agree, you should check for voltage and function at the relay for the daytime running lamps on your Astro.

But, if all else fails, the electrical shop should be able to diagnose and repair this problem.

Blue High beam indicator flashing and high beam lights and daytime running lights no longer working


Check your altenator. Mine had the same problem blew all the front headlights, running lights. My altenator was over charging the system. Sounds like you need a new altenator. Pull the bulbs to see if they are blown..if your lucky the fuse just went. Fuses #15,16,17,18 located beside the battery may just be blown also.

FUSE OR LIGHT ISSUES


If you purchased your vehicle in the States, it is not equipped with Daytime Running Lamps, you will have to purchase an aftermarket module and have them installed to the parking lamp circuit in order to save the wear on your Xenon bulbs.  Only Canadian models have running lamps standard.  As far as your clock I know that the bulbs in Infiniti clocks are notorious for going bad. You can remove the clock and replace bulbs, but I would check your fuses, there is a fuse panel down in the drivers floor kick panel. I would suggest doing a google search for G35 manual and you can probably find some site that has a PDF version you can download for free.

Daytime running lights no longer work after using handbrake.


When the parking brake is applied there is a switch that will cut off the daytime running lights, and they will not work as long as the parking brake is applied. If you have released the parking brake and they no longer work, either the switch that cuts them off is bad or the sensor for the lights is bad.

2000 Silverado daytime running lights don't work. bulbs new.


Not saying that you don't know this but the daytime lights are turned off in park.
If that is not your problem, a friend of mine uses the amber bulbs, they last longer.
