So I think I may have a bit of a water leak either at my rear window, or at the cab vent on the passenger side. I've replaced every piece of weather stripping on the door, but I still have water filling my passenger side door sill (I removed the plastic panel that sits there), so I believe those are the only two places left to leak. Anyway, I want to check it out before paying a glass place to reseal my window when it may not be the problem. I am curious as to how I should proceed to remove the rear panel against the back wall of the cab, and maybe the rear seat, in order to diagnose things.
I remember my back seat being a PITA, but I just started pulling bolts blindly. I took the back rest off the other night. If I remember right all I had to do was yank up like a SOB and the bottom of the back rest pulled out toward the front. Probably not the right way to do it, but mine came off and went back on with no problems.
On an E99 SuperCab there are 4 fasteners on the inboard side of the seat mounting bracket. A T55 or T57 at the front of bracket (second pic) on each side and an 18mm nut on stud (third pic) at the back of bracket on each side. I tried a T55 and it felt a bit loose so I think a T57, which I couldn't find just now, would be a better fit.
To make it easier to get out you can remove the T50 pivot bolt for the bottom seat (first pic).
The backrest pivot bolt is near impossible to get to with plastic trim in the way, but the 18MM nut can be removed with backrest in place.
The upper backrest pad is held with plastic prongs in tension clips and simply pulls off.
I have never had the rear panel off so you're on your own with that.
In the third pic what appears to be a second bolt on stud is just a reflection in the seat monting bracket.
Wow thanks a ton Payson, looks like I will have a little weekend project. I am going to look around down there today with a really bright flashlight during the day when I have more light, I checked the back of the cab between the body and the bed and the vents appear to be perfectly seated, so I'm begining to believe the window is indeed the culprit.
You could always have someone grab a garden hose and wet around everything while you sit in the truck and watch... Just a though... and its free
Did try that, but it's a bit tough to tell exactly where it's coming from, whether it's the vent or the window, would be a lot easier to say for sure if the rear interior and sound panel was off. I think my best solution is to get it fixed and then get the hell out of Seattle for good.
