Like I have stated a few times during my newbie back again post and this thread, I used to run repair shops but have been away from them since 2008 and am a bit rusty about what I may or may not have seen in the shops at the end. Since the 2011 Tahoe came out 3 years later I need some input. At the back hatch there is the gold Chevy Bowtie emblem that is affixed to the upper license plate cap and as far as I remember there is only license lights in under there. What I did notice about the emblem is that it is discolored in several places leading me to believe that water has gotten in there. Besides the license lights, is there anything else in there that could be effected by water soaking thru all that?
