hey guys is there any way to turn off the automatic headlights. my truck doesn't have the off option so if its dark out they are on. i just want to be able to choose when i want my headlights on. so is there a sensor i can unplug or trick? surely i cant be the only guy here that is bothered by this haha
99 model? hit your e brake one click I do believe
Hitting the dome override a couple times usually does it. Worked on my 02 Tahoe but not my 99 Silverado
Dome override will not work on a 99. The e-brake trick only works if you kill it, push it down one click, and re crank. however it will
chime at you as soon as the vehicle moves. So to answer your question, No, you cannot turn the headlamps off in a way that is not
annoying as S***. Very frustrating, i know. In 2000, they changed it to where pushing the dome override will kill the lights.
damn it GM you bastards! haha i might try and track down the sensor its self and see if i cant figure something out. ill make a thread if i figure it out
nevermind i found an old thread on a gm off road form. this does the trick
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.
Locate 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 ornament.
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!
