It very well could be. I had the same issue. I replaced it with one of the cheap replacement parts from the local parts store and that lasted all of a couple weeks.
I cured it by getting an original OEM piece from a different steering column, still going strong. Those replecement cams are junk, IMO.
One other thing you might check first it the connection behind the driver side kick panel, there is a connection there that can get boogered up. Also make sure you have good CLEAN grounds at both lights in the back.
