I popped my trunk today and found a puddle of water. I examined the area and noticed the rubber grommet on my rear wiper moves around and allows water to enter my trunk. Does anybody know how to fix this or has anybody else had this problem?

maybe get a new rubber piece from somewhere, or just try to silicone yours where it would stay still and not leak?

 

Bump,
I'm having this exact same problem. I just discovered it the other day and I have not looked into fixing it yet.
+1 for input from anyone that has already had success fixing this problem.

 

I would think it is safe to say you just buy a new grommet and replace it? There should be a reference guide in the service manual on how to remove the wiper and re assemble it.

 

if you pull the plastic cap off the wiper blade... remove that 10mm nut, pull the arm off, then there is a larger (24mm MAYBE) nut.. likely it has worked its way loose, tightening that down should help the issue as well. Maybe you need a new gasket/grommet.. but if this is loose (alowing the piece to move some) even a new one won't fix the problem, unless you tighten it down.. Not 'crack the glass' tight.. just a good solid snug. I don't have the manual in front of me for the torque spec.. but try this... then come back and 'bump' the thread.

 

What he said^ And don't crack the glass!
Some plumber's goops may help here too.
