2000 Gmc Sierra automatic light issues
 

I have a 2000 GMC Sierra 4x4 5.3l V8. Recently I have noticed during the day my automatic lights are not shutting off like they are suppose to. I think it mite be the sensor on the dash but I can't figure out what would cause it to go out. Any other ideas of what it could be or suggestions?

Thanks! I'll post pictures soon!
