I just bought a 99 model Z71 (new body style) and the headlights are always
on. anyway to turn them off? is there a DRL fuse or something i could take
out? Also, when i reach 25-30 MPH, it locks the doors, when i turn it off
the doors stay locked. is there any way to stop it from locking or how to
make it unlock when the truck is turned off?
Re: " Damn pain in the ass about the door locks tho. Wife's machine
locks em when you put it in gear, and like yours they stay locked. Still
it might save a car jacking. I suppose that is why they do it. "
His(O.P.) lock when he reaches 25 MPH.I think that is to decrease the
likelyhood of the doors opening in an accident(?).Anyway a car-jacker
would have to be pretty fast to bother him at that speed.
There are three kinds of lies; lies,damned lies,and

Disabling Automatic (Rolling) Door Lock Feature (Service Procedure to

First, if your headlights are on "all" the time, you probably have something
covering the sensor. Its a little thing near the center of the dash -
towards the passenger side. There is no way to change it. If its daytime,
the DRL's are on, and if its dark, the headlights are on. I bought an
aftermarket gizmo that put a switch in my dash right next to the airbag
lock. It turns off the auto headlight sensor so now my headlight switch
works. The door locks are not programmable on the 99 models. I rigged mine
to unlock when I put the truck in park. My headlights have all four on when
in high beam mode. My fog lights are on with the low beams. The company I
bought these things from is out of business - I think it was just a guy
selling from his garage. You will get a bunch of responses about DRL's and
auto headlights. If you don't want DRL's, remove the bulbs. Notice they
are off when the truck is in park. Your headlights are on if the key is on
and its dark enough outside.
I know I've been lookin for a way also. I just like the look of a
vehicle with just the running light on and maybe driving lights. I
would like to set in my truck (on the set) without the "BRAKE" light
glowing at me because I wanted the DLR's off!.
I think the DLR's are kinda dull looking too. If I have to keep them,
can I replace the bulbs with bright white bulbs?
Second question, were can I find a replacement grill frame? My frame
has the white spots were the hood drains (above the headlight.)

The OP has a 99 full size. I think the s-10 still uses a reduced high beam
as its DRL. They might stay on when the truck is in park. The full size
uses a 4157 - the same intensity as a turn signal bulb. I changed mine to
My neighbor has a 2002 (I think) Sierra, his go off when the truck is
in park, he found it VERY difficult to figure out which DRL was burned
out. Yeah, most S-10s use reduced-intensity high beams, the ZR2s
(like mine) use full-power low beam...
