Running lights....
Anyway...this is how you get to the DRL's:
Right below the DRL's ( in the front end of your car's body ), you will see those smaller holes ( vents ).
Stick your hand through the holes ( vents ), and move your hand upward...so it is directly in back of the DRL.
You will feel a wire ( harness ) going into the DRL. At the end of the wire ( harness ), you will feel a plug. Grab the plug, and turn it, then pull it out.
You will see a bulb attached to the end. Take the old bulb out, put new bulb in, and then just put the plug back in. When you put the plug back in, make sure you turn it the opposite direction of when you pulled it out. You will feel it fit snugly in place when you turn it.
This is very very easy to do....but you have to have flexible wrists and good fingers. If you get some fat *** to do it...it wont work, cause there wrists will be too big....
Hope this helps. I dont know WHY GM made those DRL's such a pain in the *** to change.
I had some trouble doing it at first, but its simple. The most difficult part is that the socket dosent come all the way out of the lower vent...so its kind of difficult to be ablr to hold the socket and put the new bulb in at the same time.
good luck
