This 2003 Chevrolet Silverado came in with both daytime running lights inoperative. In order to access the DRL bulbs the headlight assembly has to be removed first. It is pretty simple. Locate the retaining pin and lift up the lever.
With the lever lifted up the pin can be slid out towards the center of the grill.
Now that the pin is removed the headlight assembly can be tilted forward.
Once the assembly is far enough out the wires can be disconnected from the bulbs.
All right now the headlight assembly is out of the way you can access the DRL socket from the rear of the lower light assembly. However it is pretty easy most of the time to just depress the latch at the outer edge of the light assembly.
I am using a screw driver to depress the latch and then the assembly will come out quite easily.
I removed the socket from the lens assembly with the intention of just replacing the bulb but I found that the socket was damaged, burnt out.
I spliced in a new 4184 socket assembly. Installed a new bulb, placed the socket back into the light assembly and reassembled the truck. Another one fixed.

You have let me realize that I did not put enough information on actually splicing in the new socket. There has been some confusion so I have added another post on that subject.

You mentioned DRL module, where is this module (2004 Silverado)? Got similar problem: bulbs work, no voltage to socket, voltage at fuse, 8833 fuse box relay working, so what else could it be?
Thinking about running a bypass wire from fuse circuit to DRL harness (test wire has DRL lights working).
There are different bulbs for different years but the 4184 socket does fit full sized GM trucks from 99 to 07 classic. It definitely fits a 2003.
I have 2003 Silverado myself. In the manual it has the DRL bulbs listed as 4114K, Would the assembly still be the same as the 1st one shown on this? If anyone knows please let me know. My DRL been burnt out for years. Just tired of it looking like that.
The first thing to do is determine if the problem is related to the remote start system. When you refer to tyhe running lights, do you actually mean the daytime running lights or the tail/park lights? To continue this conversation please email me at sparkysanswers@gmail.com
My 99 Century seems to have something of this sort of problem. The exterior running lights do not come on when starting the car or by using the headlight switch to override the daylight sensor. The kicker to the whole thing is that everything works fine when I use the remote start. As soon as I put the car in gear after using the remote start, all the lights go out again. What do you think?
