This afternoon driving home from work I noticed my left Daytime Running Light was out. (Saw the reflection in a vehicle in front of me at a stop light).
Exactly how do you check the light? The bulb appears to be OK but the only way the lights are on is when you are driving. Putting the vehicle in park, the lights go out. Putting the emergency brake on and the truck in drive, the DRL's don't come on.
I pulled the vehicle in the garage and could see on the wall the left DRL was not on. But I would like to check the voltage at the plug to make sure it is getting power.
Any ideas?
Thanks
