Water leaking into the cab.

[biggdadd58]

My 2016 3500 just started leaking into the cab, above the driver visor, running down the pillar and onto the door speaker. The light and antenna seem to be sealed to the roof and the sun roof looks to be closed. Any thoughts?

If it isn't the usual culprits you may want to get your windshield removed and then reinstalled. Very likely it is leaking around it.

If you have a sun roof the drain tubes might be clogged. The path the tube takes follows down to the area you are describing so my guess is the clogged drain is allowing water to flow along the outside of the tube. I would still check the antenna while you are at it too. My antenna seemed to have a good seal and wasn't leaking, but when I removed it it had quite a bit of dirt and debris under that could easily wick water into that area...

Sunroof tube did not seem to be clogged. I will check on this the next time it rains. All other stuff seems to be ok.

If you have cab lights it's probably that. Take them off and apply a very thin coat of clear silicone on the bottom of the rubber pad. I've had to do that a couple times. Car washes are hard on those
