I carry stuff under my rear seat and I was looking for something today and it's all soaking wet! There's a puddle of water sitting there after I pull my wet stuff out. Has anyone else had this problem? The truck is a '08 quad cab with the rear electric sliding glass. The water soaked area is under the passenger rear seat. I've noticed it once before but it wasn't a water puddle, I thought someone just spilled a little water on the seat and it made it's way under.

 

With the solid glass and manual sliders it's always the 3rd Brake light, with the power window it could be either. I'd say to take the screw out of the brake light and silicone the **** out of it and put it back on - and hope that's it because I don't think anyone has solved the power slider leak short of replacing it.

Symptoms are the same, when the brake light leaks it goes around the window and underneath it to the same place as when the window leaks...

 

Thanks, I'll pull the brake light tomorrow and give that a try.

 

Yeah I had a 3rd brake light leak once too. Very frustrating to say the least. But I tightened it down some and it went away
