Gentlemen,
I have a 1999 Silverado 2500, 6.0 liter, 4x4. Recently, when I activate the left blinker, the left blinker light will not make and break, but will stay on continuously and stay that way even though the turn signal arm has returned to its neutral position. I suspect a faulty turn signal relay. Any thoughts on the matter before a buy a non returnable electrical item. Thank you.
