Guys,
I have a 2003 Silverado 2500 4X4 (Canadian version) which has the "Auto Headlight on" function ... What I would like to know is if any of you guys have disabled this function ? And can you do it with the original headlight switch? or do you need to replace it with a US switch ?

Thanks for any responses.

AL.

 

i have it on my ss, and its annoying...would be nice to turn off

 

why does it bother you guys?

military bases?

just press dome overide 4 times in a row and it will deactive the autolights, but when you take out your key, and put it back in the ignition and start... itll be back to normal.

so you have to do it every time

 

Just turn the **** down to the left, (it wont stay down it will come back up) and it will cut the lights off

 

Thanks guys,,but no good,neither of those 2 work ??
I have read somewhere that the Canadian version is different in this area,I think. It seems that nothing less than direct sunlight on the sensor will turn them off !!!
It is something that we are not used to down here,and is real annoying when you can't turn them off !!

Appreciate any more suggestions on this....

Cheers

try doing what 03 said but 3-4 times consecutivly. just a thought dont realy know though. knowing gm you prob have to turn the blinker on and honk the horn 2 times.....

 

there is a way to put a resistor in the circuit to disable the auto headlamp feature.

 

You can put a resistor inline with the connector that hooks to the twilight sentinel. I found this info a while back on disabling the Auto Headlights:

"Listed below are the instructions that I came up with about a year ago to disable the auto headlights on the 1999 Silverado/Sierra new body style trucks. I have had mine like this for nearly a year and it works great. There is a little work involved, but it sure beats paying $90 for the little pushbutton gadget from R&D Truck Acc., (no offense Darrell). Keep in mind that I am talking about the automatic headlights (twilight sentinel) and NOT the damn DRL's!!! Yes, I already know there is a fuse for the DRL's under the hood or you can just pull the bulbs out. Good luck and let me know if you
need any help. Later,


For those that don't know, the twilight sentinel is the feature that automatically turns on the headlights and taillights when it starts to get dark outside. I like this feature alot, but I wanted to find a way to disable it when hunting season comes around. I also like to use just the amber colored running lights in certain situations. These instructions are for my new body style '99 Silverado regular-cab, with LS option package.

There are two ways that you can do this procedure. The first one I have listed is how I did it
the first time not long after I bought my truck. The second way I have listed is how I did it a few weeks ago just to see which way would be easier. I personally like the second way better, but read both ways that way you will know everything that needs to be done.

Things needed are: One 1.5K ohm 1/2 watt resistor (Radio Shack, $0.49 for a package of 5), electrical tape, pliers, and having small hands is a plus. A small socket set with ratchets & screwdrivers will come in handy too. Another nice tool to have is a dental pick. It makes unplugging the connectors a lot easier.

Here is the first way:

#1. First thing to do is to pull off the face of the dash and get it out of the way. It just pulls right off and snaps back on, no screws, bolts, or anything like that. It helps to lower the steering wheel all the way down and if you have an automatic, put the shifter all the way down into 1st. Be sure to set the parking brake, just in case! Next, pull out the radio, (push down on the two black tabs that are kind of sticking out on each side & pull the radio towards you at the same time), and unplug the connector and antennae and set it out of the way. You should be able to see the bottom of the ambient light sensor that is near the front of the dash,(it has one gray wire and one white wire running to it). Try to twist the sensor to unscrew it from the dash, (I had to use pliers from the top side on mine). Once loose, pull the sensor down from the hole in the dash,(it can not be pulled through the top), unplug it from the the connector, (not easy), and remove. Don't drop it or it might be lost forever down in the dash somewhere. Now take the connector plug-in (the one with the gray & white wire) and route it up through the hole in the middle of the dash for easier access to it. Now you can plug in the resistor into the connector, (I found that it works best to fold the wires of the resistor over itself once to be sure that the wires are making contact to the connector), and tape it up with electrical tape. Be sure to test it out to make damn sure that it works, (hint: Release the parking brake or else you won’t know if it is working correctly.). If it is not installed correctly, the headlights & taillights will come on whenever the truck is turned on, day or night. What you do next is up to you. You can either re-install the unplugged light sensor to fill in the hole in the dash or leave it out and have a hole in the dash. Put the radio and dash back in and your done!

I've had mine wired this way for months and have had no problems at all, it doesn't get hot or anything and I have total control of the headlights.


The second way to do this is…….

#2. Another way to do this is to remove the whole upper dash unit. It really wasn't that hard to do and it makes it ALOT easier to get to the ambient light sensor. You do not have to remove the radio if you do it this way.

First thing I did was remove the face plate cover that covers the radio, gauges, etc. Then removed the 5 nut screws that hold the dash cover to the instrument panel. Took out the screws that are on each side of dash, (in the door jam areas, covered by the fuse panels). Removed the plastic A-pillar covers, (they just pop out from the top, be sure to put the metal clips back on the cover before re-installation). Got a butter knife and popped out the 2 A/C vents on the passenger side and removed the 2 screws that are in the holes there. Pulled out the "handle" that is directly above the passenger side airbag, (if you look inside the A/C vent holes you will see a white plastic "clip" on each side that is holding the steel rods of the handle, push these in slightly and pull the whole handle out). Double-check for any screws or clips, just in case I forgot to mention some.

Now the hard part. You have to pull hard, straight back on the dash cover to get it out. I started on the driver side and worked my way to the passenger side. I put one hand between the bottom of the windshield and the front part of the dash in the driver side corner between the windshield & bottom of the A-pillar and pulled it straight back to "unclip" it from the metal that is holding it there. You have to use a little force to get it out, but you will hear and feel it pop when it gets out of the first clip. There are 5 or 6 of the clips that the front part of the dash needs to be “unclipped” from. There are also 3 small clips that hold the dash to the top part of the passenger side airbag cover, they don't take much force to be popped out. The airbag stays in place. Don't pull too hard or something might break that you don't want to break. After you unclipped all of them, you can pull the dash back a few inches and flip it up a little bit to get to the light sensor and unscrew it from the hole, (twist it a 1/4 turn). Then you can take the whole dash completely out of the truck.

Unplug the light sensor from the connector with the white & gray wires. Put in the resistor, tape it up, test it out and put everything back in the way it came out. Putting the dash back in can be a little tricky. Make sure everything is lined up right and pop it back into place. Put all the screws back in and snap everything else back on and your done!

I wish I would have done it this way the first time, it is alot easier than fighting under the dash trying to unplug that damn sensor. You don't even have to take the radio out! I didn't break anything while doing this and I was kind of rough with it at first because I wasn't sure how to pull the dash out. It took me a little over an hour to do this, but I could probably do it in 15 minutes now that I know what to do.

Some truck owners have had to use different kinds of resistors, (different amperages, wattages, Ohms, etc.), to be able to disable the auto headlights. Most owners, including myself, have had the best luck with the resistor mentioned previously.

Some folks have added a toggle switch, or something similar, to the wires of the light sensor. This way they can choose between having the auto headlights operational or have manual control over them."

 

Wow, thanks guys ! Guess I'll try the resistor deal....
Now,,,,,how do you get rid of that pesky door chime ?!?!?!?!?
