A Pillar Leak Not Sure of the Cause

I didn't check my A pillar to see if it was wet. Next time I go through the carwash or it rains I may have to check that area as well. Let me know what you find and I'll do the same and we may be able to help each other out.

 

Double cab?

it’s gotta be the roof rack plugs. mine does this on the drivers side, only a couple times a year so I just shrug it off, nothing really that wet and the weather techs see more moisture from my boots anyway

2011 DCSB, no moonroof, I added a Baja rack

 

Got the truck back yesterday and they still couldn't find the leak. They waived the diagnostic fee and only charged me for a single day on the rental, so that was cool. They said if it happens again to bring it back ASAP. It rained pretty good last night and it looked fine this morning, so I have no clue what the deal is.
