Tons of water INSIDE rear doors..?

[GMTfour100]

2013 Silverado Crew Cab

 

After raining for a week, I could hear water swishing around when I hit the brakes or accelerated. 

 

I saw some water dribbling out of the rear doors... I pulled back the lower/bottom weather seal and water started literally peeing out of the push-pin fastener holes. The front doors are bone dry.

 

Each door also has two rectangular drains/plugs... I've pulled out the plugs to help drain in the future, but how is water getting in there??

Water gets in from around the window seal on the bottom if that makes sense. Lots of vehicles will allow water in this way. Both of my GMT-900 trucks did this, I made sure to keep the drains in the bottom two corners of each door clear of debris.

Yep around the windows. Doors aren't hermetically sealed. Keep the drains clear

Of course, that's understandable.

 

My concern is why only the REAR doors were filled with water, while the front doors were totally fine?

The drains are clogged in the back and the fronts are not , If it bothers you that much pull the door panel and see whats clogging the drain holes

I had this problem early on with my 2010 rear doors. I removed the rectangular plugs and they are still out. I clean the holes regularly, especially after having my truck resprayed with rust treatment. no problems since.
