Do you know how to test automotive electrical circuit's using a wiring diagram an a DMM - digital multi-meter ? Do you know what a factory diagnostic flow chart is ? This will not set any diagnostic trouble code's in the BCM - body control module . Looking at factory symptom chart , their is no diagnostic trouble chart for your symtoms . Have four choices .
Hazard Lamps Always On
• Hazard Lamps Inoperative
Turn Signal Lamps and/or Indicators Always On or Flashing
• Turn Signal Lamps and/or Indicators Inoperative
Which one would you use to diagnose this problem .
Or would you just view wiring diagrams an wing it ?

How do you get access to the day time headlight bulbs to replace them on a 2004 Chevy 2500 HD crew cab.


Pull on the flat "clips" to unlock the headlights, remove the headlight assembly. You can then access the DRL bulb sockets, squeeze in the tab on the socket and twist a 1/4 turn to release the socket (clockwise as viewed from the front of the lens).

First try rotating the tires to the rear. Does it go away? If you apply the brakes does it pull to the left? Could be a draging caliper or the slides may be hanging up.
