2008 Tacoma Water Leak

Hey guys, my area has had a bunch of rain recently and noticed that the passenger side to the middle of the back seats are wet. I can’t figure out where the water would be coming from. Any suggestions?

 

Check the passenger foot well fire wall.
You will need to pull off the floor liner there is a few holes with rubber grommets holding it in.

A easy culprit is often the AC drain hose. Or similar grommet.
A more painful culprit The antenna mount can also be the cause leaking down the A pillar.

You may also want to look at the body from inside the fire wall and see if you have a crack there.

If you have a friend, ask them to hose down your engine bay, working your way from the bottom to the top. While you are inside observing and or feeling for leaks.

 

middle to back, 3rd black light and the roof especially were the roof rack would mount

 

I was able to take a flashlight out and it looks like there is drippage from the rear passanger side up top

 

Im sorry, I thought you said foot well. derr...

Do you have a roof rack?
The only possible factory holes other than the door seal and (rust...) is the roof rack nuts, tail light, or sark-fin antenna (if equipped), Vent holes (these are essentially check valves), and other grommets in the cab area.

 

no sir, no roof rack. It seems like from a lot of people having the same issue, it’s the 3rd brake light up top leaking. I am going to try getting that replaced and hopefully that solves my issue. I’ve had the truck since 2013 and have had no leakage issues before but it’s getting up there in age so I guess I should be expecting small things like that to happen
