Electrical issue - one light won't shut off


Recommended Posts

Good evening,

 

I have a 2011 GMC Sierra 1500 crew cab 4x4 with a 5.5' box.

 

Everything is stock - no mods at all.

 

This afternoon, the truck was parked, not running, keys removed. The fog lights were coming on and off intermittently. Started the truck and shut it down. The good news was that the fog lights are now off. The bad news is now I have the left front signal light on the grill side of the left head light -both bulbs- lit at all times. Keys in / keys out it doesn't matter. There's nothing I can do to make it go off. I had to pull the battery lead.

 

Looking for any thoughts.

 

Incidentally, all service on the vehicle has been by the dealer.

 

Now I'm just spouting info that probably doesn't matter... I'll hit the post button now...

 

Thanks in advance

 

Trevor

BCM controlled , Nothing you can do as a truck owner I'm afraid , you can get service info and look at a schematic but in the end ... It's dealer time for a scan , please post back what they find ,
