Water POOLING on driver side floor mat

[Owens45]

I have a 2014 crew cab Silverado. I bought it used with 29k miles 2 years ago. Last year when we got a good rain I noticed water dripping from under the dash and pooling on weather tech mat. I’ve blown out the sunroof drains. The headliner does not get wet when it rains. So that basically rules out the fin. I was in the truck when it was pouring and pulled the pillar off, no water. I can’t seem to track down what may be allowing water in. I’ve looked up under the dash while it was dripping and it looks to be coming from pretty high up under there. Just drips down and pools on the floor mat. My drive way has a slope and when I back down it with the front end being the high end it doesn’t do it. I can’t figure it out. Any help?

Could be around the windsheild.

Check the Fin antenna for the Sat.   It may be running down the headliner and pillar.

Def the xm antenna. Same problem. Water dripping by the emergency brake

But I’m getting no water on the headliner or running down the pillar? Still could be the antenna?

My headliner was only a little wet

How do you fix this? Replace the antenna? Tighten any bolts or silicone?
