I have a 99 Silverado and I hate the automatic headlights, It does hace a dome override button but the dealer said it doesnt work for the lights.  On my 01 Tahoe if I press it like 4 times they shut off.  How can I get rid of the automatic headlight feature on my silverado?  I know if I press the E-brake a little they go off but then I have the red light flashing "brake".  any other way?

KMT...You could do the R&D headlight controller or

go to www.lightsout.org

Free advise there to turn off the auto ons and DRLs.

I used it to switch the wires on my 01 headlight

switch to turn em' off....Fast & easy no cutting !

Check out mountianeer toms web site for pics and

info.  Its in his profile....geo

Have you tried swapping switches to see if the 01 fits?  Then you could use the dome override method.   Although, I like the R&D headlight controller looks.  I wonder which method is cheaper.

JUst my two cents, but I really like the auto lights, I have not needed to touch the switch other than to test it when I bought the truck.

I'll try to explain this as clear as possible, but if you have any questions feel free to mail me.

 

Basically you will need a pair of wire cutters and a 1.5K ohm 1/2 watt resistor that you can get at Radio Shack.  Electrical tape and possibly some wire nuts will work to wire in the resistor.  You can solder the wires if you wish.

 

You may want to remove the neg. battery cable to assure you don't do any unwanted damage to the electrical system.  This is not necessary, but a good precaution to take.

 

First locate the Body Control Module (BCM) which is under the dash, below the steering column.  Laying on the floor, this should be visible without removing any dash panels.  You should find a purple connector (C3).  Unplug it.

 

Located the white and gray wires (A4 and A6).  I don't remember if white is A4 and gray is A6 or vice versa.  It doesn't matter anyway.

 

Clip these two wires that are coming off this plug (C3).  Leave a few inches to work with.  Tape up or place wire nuts over the other end of these wires that go up under the dash(they go to the light sensor).  You have now removed the light sensor from the electrical system and is now just a dash orniment.

 

Connect the gray wire from the plug (C3) to one end of the resistor and the white wire to the other end.  Make sure you tape up all wires to prevent a short.  You should now have a gray wire coming from C3, going to one lead of the resistor and the white wire from C3 to the other resistor lead.  Plug in C3 to the BCM and replace the neg. battery cable if you removed it.  Start the truck and make sure the lights are off.  Throw a dark towel or something over the light sensor on the dash and verify the lights stay off.  Try your light switch that has probably never been used and that's it!

 

Shouldn't take very long after you find the wires which are right in front of you.  Much easier and quicker than dismantling the entire dash to get to the light sensor!  On my '99 I pulled the radio and reached my hand up to the sensor.  Very tight fit.  On my '02, I found a brace behind the radio which prevented me from getting to the sensor.  That's when I found this simpler procedure and did it in minutes.

 

Any questions, give me a shout.

it should work for all of the 99-02 trucks and maybe even the 2003's.

 

I for one love the auto headlights.  Now that I've had them on my truck and now on my Grand Prix I don't think I could go back to actually having to turn them on.

 

But, then again I'm just lazy.

Yeah, I love my auto headlights! :thumb:   I had them on my Camaro and got spoiled.

 

There are times though that I would like to sit/drive without any lights on and would like to be able to disable the DRL's and auto-on lights.

 

I am leaning toward the R&D headlight controller because of the quality I have seen in their other products/instructions.

Got a question, probaly a stupid one but what happens to the DRL's do they still work. The answer is probaly yes but I just wanted to know for sure. Thanks

I like the auto headlights, but they should have put a disable setting, like the '03 models for those who don't want to use them, or just disable when you need to.  Afterall, they're not required by law (in the US), so why not a disable?

 

The DRLs don't bother me either, and I'll get ambers for them when I burn one out!  :cheers:

Just snip the wire connecting the light sensor to the BCM.  That oughtta do it.

Better yet, instead of snipping it, use a tiny jeweler's screwdriver and release the latch that holds the terminal in the connector housing.  Then just tape it up.  If you ever sell the truck, you'll then be able to snap it back into the connector housing.

The wire is a white one going to pin A6 on connector C3 of the BCM.  BCM is located under the steering column.

the dealer told me that if i cut the sensor wire it would do the opposite and leave them on all the time.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Were you looking at the HD trucks on the GM website or the half tons as that makes all the difference. As far as I know there are only two options for the HD trucks and that is the standard 2 speed transfer case or the 2 speed transfer case that has the added 4 high auto feature and they put that transfer case by default into the LTZ and High Country although its optional in the LT and not sure if its available in the work trucks.    The half tons, that is where its been a total mess in my estimation for a few years now with most trucks below the top trim having the single speed transfer case as standard but with the option of having the two speed such as one would get by choosing the Z71 package, however then not being able to get the two speed transfer case with the towing package unless it was a higher trim truck AND had the 6.2 gas so one could combine the towing package gearing diffs with the two speed transfer case. Having said that if its a trail boss package then it gets the two speed transfer case but not necessarily able to get the tow package as it would depend on trim level and engine chosen. Believe me, people have bought the GM half tons assuming "of course it will have a two speed transfer case" only to find out after when they really pay attention to what they now own .... crap, there is NO low range !.    I don't believe Ford or Ram have gone that way yet with their half tons but like I say its been a few years now that GM has done this with the half tons.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      My office is slowly filling with Blazer parts. Getting ready to do the big bang of repairs. Intake (second time), water pump, radiator, hoses, and I'm going to re-seal the timing cover where someone went hog wild with silicone. Might as well, because I don't think that's done right.   There's a local tow yard that I didn't realize also has quite the inventory of junk vehicles. This is an old school junkyard. No waivers. Cash only, you were never here if anyone asks. Don't piss off the owner, or you'll end up in the back of one of those cars, headed for the shredder. And if you see something, don't snitch. Cars stacked double high, wasps nests, trip hazards and junk everywhere. I found a few little odds/ends for my Blazer. The $20 I spent was worth the experience alone. But I was never there. What yard?   I officially love/hate this truck. It's so out of my wheelhouse, roughest vehicle I've ever owned. Every. single. repair. -is so hard-fought, everything that can go wrong, goes wrong. Currently in a hate phase, and kind of wish I was closer to sending it down the road with a lucky new owner, to be honest. Preparing for the day when I tear into this thing...lots of pre-funk with Ibuprofen.   Rock Auto sent me a bad reman rear wiper motor. It was a bear to install. The tailgate in these things has about eleventy-billion fastners and pieces and things that need to be uninstalled/moved just to access the shoddy rear wiper motor. The casing on mine was cracked clean through, btw. Nice, GM, nice. SO I got this new motor installed, hit the switch, I see it wig-wag (without the arm installed) and think I'm golden. Reassemble everything. With the wiper arm installed I gave it one final test. Time to clean up and take the other half out to dinner, collect a paycheck, right?   Nope. I hear the plastic worm gear stripping as the arm hung up. Just like my broken motor. Weak/old and shredding itself internally. I can assist the arm and the range of motion is normal, and it parks correctly. It just doesn't have the poop to actually sweep the arm with a blade on it. Oh, hell. Turned the key off and shut the shop door behind me. I get to do that over again, too.

      AFM Disabler Question

      By BlueV8 · Posted

      A complete delete is the most thorough mechanical solution, but it is also major engine work. On a quiet truck that is still under extended warranty, opening the engine purely as prevention is difficult to justify. A plug-in disabler stops commanded cylinder deactivation, but it does not remove or repair the collapsible lifters, so it should not be treated as failure insurance. I would keep the oil full, document the maintenance, and have any persistent tick, misfire, or loss of power diagnosed promptly. If the engine eventually has to come apart, that is the logical time to compare an OEM-style repair with a complete delete. The right choice depends on the truck’s symptoms, warranty status, expected ownership period, and whether the engine already needs to be opened. We explain that decision in more detail here—full disclosure, this is our own guide: https://www.bluev8.com/blogs/news/do-you-actually-need-an-afm-disabler   One exception: some 2021 L82/L84 trucks have RPO YK9, meaning cylinder deactivation was already disabled in the factory ECM; on those trucks a plug-in disabler is redundant, although the AFM/DFM hardware remains inside the engine.

      Help purchasing a touch screen digitizer

      By mark249 · Posted

      Brought my 2015 Colorado into the dealership to check my touch screen issues, had that ghost touch thing happening. They said I needed a new touch screen and they could either order me one for $500. The lady at the service deck was nice enough to tell me I could order a touch screen online for less, she did stipulate that the touch screen had to be factory OEM, you can't pair an aftermarket screen to my radio seeing it was 2015, it had to be a GM factory OEM only. I found a few on Amazon and Ebay by the numbers on the back of the old screen, DJ080PA-01A GM# 22740886, Some said "OEM" in the description and others just said "Replacement". Would a replacement be the same as a OEM as long as it had the same numbers on the back of the screen? In some of the descriptions they also show different brand names but same numbers, is that an issue?
