Chevy refuses to help with DRLs
 

I don't know if this post falls under this forum, but if anyone is thinking about trying to get help from Chevy with how to turn off your DRLs or anything else, don't bother. It's a safety feature and you can't turn it off. You are then transferred to a few different people through email, back to the original person, who then tells you that they will not give you the information you want and that they are closing the request for information. All I wanted to know was how to turn off the DRLs, which are only a safety feature as a matter of opinion (which I told them). They also responded to my question about whether my car can be towed flat by quoting the owner's manual, a simple yes or no would have been just fine.

Get the shop book, makes life way easier for stuff like this. You might be able to find it at your local library

Have you tried:

lightsout.org

it may just be a relay under the hood, or a fuse somewhere.

Good URL. I was thinking about the same thing.

If I were Chevy I wouldn't give you any advice either (liability issues). But, if you made the claim that you were troubleshooting an electrical problem, you might have been able to coax out the DRL-off info, ;) .

If you are a w-body, try the panel in the dash by the door. It's in there. CHeck clubgp.com.

im sure there is a fuse you can pull. my 98 blazer had it. you could also pay buku $$ and take it somewhere with a Tech II and turn it off through the BCM (body control module) some of GM's cars have a DRL module rather than a line of code in the BCM. my blazer had the option through the BCM. but my 08 aveo had a module. but its also a daewoo.

My 96 Chevy truck had a module located under the dash that I promptly unplugged. No more DRL. :D

Going to do the same thing to my newly acquired 96 Metro, as soon as I get the notorious burnt out headlights fixed. :lol:

Hi Mr Chevy, my DRL's wont come on, can you tell me ......................

all cars have a schematic
get it.
all puplic libs have them , even online,

need a link and pw, just PM me.


you really dont need chev.

The FSM has all this too.

My moms H-body Bonneville had a resistor under the hood. When disconnected no more DRLs

each car is diff.
each car model is diff.
each year is diff.

if you post a question and want an accurate answer,
please state the mfg name, model , engine size , year and body type.
oh, and the country the car was delivered to.
Lighting laws vary greatly, by country.

i can then look up the model on-line at my public library ,called ARRC.
then look for the head light page schematic.
look at it for 1 min. and tell you the answer.
or
you could ask and I can send you the link, and you could look it up your self.

why guess?

i can do , usa/canada cars.

hope that helps someone.

never ask some one a question , they can't answer.
asking Chev. how to kill you self is kinda , silly. right.

they wont answer any questions on how to modify your car .
the reason should be obvious.

(not talking hub caps here, mud flaps, etc)

what model again? I'll ask my cousin who's been a master certified mech at Chevy for over 12 years. He used to say people wanted them turned off and he just plugged in the shop's computer scan tool and shut them off. It's a driver preference option, not legally required. This might not always be possible, but I'll find out.

each car , each manufacture has different , methods and designs.
you can get a FSM on fleebay and never need to talk to Chev again.
become self sufficient.
Not to mention, Chev. forums galore. and ALLDATA.com

teach a man to fish..... and all that.....

Keep in mind there are 2 sides of the OBD2 spec.
side one , we all play in .
side two, the OEM side , locked out to us.

get on the chev. forum and join, then post this question.

also it depends on the year the car was made.


before you start popping this and that off, keep in mind , if you have air bags , you just might be in for a surprise.
on newer cars, step one is " read page 1 in the fsm" tells how to defeat the airbags."

goggle mechanics dead from air bags.


safety first.

not discouraging you , I have 1 car running on a Megasquirt MS2v3.

cheers

Hello,
I have a maybe answer.
I have a 2000 Chevy Blazer LS , owner manual states push the dome override ( by the head light switch ) 4 or 5 times and the daytime running lights go off . do the same thing and they come back on . The system will reset itself when you turn the car off so you will need to do this everytime you want the DLRs off. that is what has worked for me .
GOOD LUCK>

Two incredibly easy and quick ways to do this. . .snip the cables to the DRL lights or pop the fuse.

The reason chevy won't tell you is because if you get under the hood and screw something up and die they might get sued. . .

They will always avoid talking to a non employee because there are no forms for you to have to fight through to get a lawsuit.

first off, is this a 99 monte? you never said for absolute, many cars some folks have.
you?
and 1 year newer can be vastly different.

19k upload limits me to zippo. here.
so try this.

DRL module on your 99 monte
is left side dash.
next to and mounted on EBCM bracket.


now, dont have the foggest what GM TECH tools can program or not,
but , yours uses no external resistor.
so that leaves 2 possibles.
1: the DRL module PWM , modulates the lamp to reduce current
2: or has an internal resistor, so the module must get real hot.


there it is , all of it. (sans software) in fact there is no PCM or BCM
engine or body comes to this unit so any ECU commands that can defeat this
device is false (look at print)

that leaves only 2 possibilities
1: wiggling the 2 switches like crazy and see if it has a secret back door.
2: cut wires to DRL and see what happens. (expensive if you bust it)

the switches to wiggle are combo HL,park ,off and High low and Hand brake.

that is it.
cheers.

do not snip cables or wires. but please look at the schematic, click link DL and extract its a zip file.
and make a suggestion (facts ) what to cut. as you can see , if you look
cutting the wires, kills , normal ops.
if you cut the low beams , no more low beams.

gee.

The other easy option. . .remove the bulbs. Its not likely to short anything otherwise its the dumbest design since series christmas lights. . .

you forgot to look again.
look at the drawing carefully, please.

see , if you remove the bulbs , you loose the normal function.
all cars are diff,diff models , and all countries have diff rules. (on lighting)
so you must get the drawings for a specific veh. before you can guess.

cutting the wire, or removing or cutting the bulb contact will kill all low beams for ever.
the DRL has 2 modes:
1: sends full power to the Low beams ( normal mode) " and a dark detector"
2: or it sends low power (voltage is less) to the low beam filaments.

that is how it works (plus some logic)l

look at the drawing and , it is exactly correct for 99 monte.

cheers/
PS: please dont drive on high beams for ever.
it could be bad for you. and others.

Really. . .thats retarded.

The Civics DRLs are a different bulb. Incorporating DRLs into your regular lights is assinine. . .it makes it far more likely to toast your truly needed actual low beams. . .

this is no honda , its a 99 monte.

and you are wrong (sorry) i have the lamp engineering book in my lap.
when you reduce the voltage to any lamp the life time shoots up many fold.


that is why they use a simple method,
saves wire. (copper times may million)
saves extra bulbs.
and all the effort, costs and wasted resources of the more complex.

this technique is common as nails. here.

Not having them lit at all extends the life even further.

and pardon my saying the obvious.

except the humans.

3rd rear tail light , useless (data)
DRL, life savers.

see and be seen. ( no all the idiots driving can even see)

I drove a Motorcycle for 15years, and i learned this real fast. Click.

Except for the fact that GMs use the high beams for DRLs, not the low beams. That is, the ones that use the headlights -- some GMs use the turn signals.

that is why i made the comment,
all cars, models and countries can be different.
and the lighting rules are all different in these countries.

DRL is done , every way you can imagine.

all you have to do is.
walk into any library , walk up to the terminal , and print out the schematic for your car.

on the screen, click E-sources. then AutoRepair.
behold.
your car, your drawings, no more guessing.

so before you hack your car to death , look at the road map.


gee, if the high beams were used, that is even better
after all
what do you want to go bad first.
Highs
or Lows.

think it through, and look at the design life maps on GE bulbs .
see the Life hour , on reduced current .
some are 5000 hr. at 14.7v and and 10v are 25000.
the curves are not linear but logarithmic and life extends greatly at lover voltages.
if you need the books they are free on line , just read them.

DRLs don't save lives lol.

By law if its raining you have to have your lights on. Thats the only time your light should run between sunup and sun down. The low lumen lights are not even comparable to a small glare off a windshield.

The reason motorcyclists get hit is because they are too small. At 300 feet you can fit a rider and motorcycle into the human blindspot. Obviously you can't hide them where you could hit them . . .but you might only be able to see part of their helmet with other cars and columns inside your car.

They put DRLs on so that they can tout their car as safer. I hit a car that had DRLs. Had nothing to do with not seeing them.

Most accidents don't. Most accidents are driver error as a result of speeding, unable to react quickly enough to a change in circumstances, minor twitch of the steering and over-correcting. . .Its usually not the driver didn't see the other vehicle.

It is not recommended to dim halogens since the halogen cycle will not work if the bulb does not warm up enough.

If you decrease bulb temps the filament doesn't last anywhere near as long. The hot filament makes it possible for particulate matter to condense back on the bulb. If its not hot enough the particulates won't melt fast enough, they will just precipitate to the bottom of the bulb.

Its the idea behind HID lights. They fail at low voltage very quickly
