Okay, I know this topic has been covered before, but I'm trying to gather all the suggestions in ONE checklist of places to look for water leaks coming into a Jetta II. Have I missed anything ?
- Drain holes in front of firewall on both sides, under the black plastic, check for blockages.
- Drain tubes for sunroof, check for blockages.
- Drain holes in bottoms of doors, check for blockages.
- Trunk seal: check for dead leaves, etc, blocking the drain groove.
- Plastic vapor barrier in doors: seal it to the door with RTV.
- Feedthrough for speedometer cable in firewall, seal with RTV.
Did I get them all ? I want to go through this car and fix this once and for all.
At the same time that I'm doing this, I also want to add some acoustic insulation inside the doors and cavities to cut down on road noise. I want to make sure I'm not accidentally blocking any drainage points.
