Geez...not even a year old...and my passenger side daytime running lamp is out. I have noticed on many Silverado's that they only have one running lamp on...and usually always the passenger side is out. Could it possibly be a malfuntion or just coincidental. My '96 S-10 and '00 Cavalier never burned out the whole time I owned them. What do you all think? Anyone else had to replace or maybe just haven't noticed yet? My dad mentioned it to me when I went home over 4th of July Weekend...who knows how long it has been out.
