Chevy refuses to help with DRLs

[jtgh]

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

[jtgh]

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.

[jtgh]

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.

[jtgh]

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.
