I have a 01 LT. The right fog light is functional but has no lens. I have noticed while walking through parking lots there seems to be alot of Tahoes, Suburbans and Silverado's with similar foglights that seem intact other than having no lens. I don't recall ever seeing one that was cracked or shattered, only missing completely. Do these lens just pop off? Short of replacement of the entire unit, is there a lens fix? It seems to be a strange affliction!
