I got a 2008 Silverado. When I remote start it sometimes the passenger side headlight comes on and turns right off. Sometimes it turns on and its not as bright as the other one and doesnt warm up as quick. Once i put my foot on the brake both headlights work perfectly it just that initial time when I remote start. This only happens when the truck is cold. if I drive around and shut the truck off and remote start it the headlights work fine.

I was thinking maybe the relay is going since the headlights work most of the time. If it was a ballast or a bulb I figure it wouldnt work most of the time.

Any ideas?
