Been battling the leaky passenger side firewall for a while now, and with our never got started summer, quickly turning to fall weather up here in the NW, figured I'd better fix it unless I wanna drive around with a towel on the floor all winter again. Searched the forums and couldn't find anything in too much detail so I took off the passenger side quarter panel and found the leaking pinch weld, here's a pic of where it's at, hopefully this can help anyone else with this problem.



I cleaned it up and put silicone all around it, also put a generous amount on the inside of the pinch weld which can be reached by sticking your fingers through the wiper drainage tunnel just behind the weld. <img src="/forums/images/graemlins/kewl.gif" alt="" />

Good show; is that a hole I see in the firewall grommet for the ECU cabling?

Nope, no hole, I think it's the only clean spot on the grommet! <img src="/forums/images/graemlins/lol.gif" alt="" />

I just fixed the same thing this year. I cut out the bad pc and elded in a new strip and welded the whole edge. Also took a zip cut and cut teh dranage hole much bigger and fixed a few small leaks inside their as well. and then welded the dranage hole back in. Stay away from using the silicone iv never had any luck with using it no mater how well i cleaned it up it always traped more moisture behind it and rusted worse.
