Re: wet fuse box (84A1)
rabbits leak from many places, and water dripping on the fuse box has caused al kinds of problems for me.
1-the lower corners of the windshield, flows behind the dash onto the fusebox.
2- inside the fenders in the upper corner, gets rusted out from all the water being thrown up from the wheels, goes the same place.
3-The drains on your rain tray are probably full of crap, there is one on each side, clear them out.
4-pull your door panels and make sure the plastic vape barrier is up.
there are more but those are the main places to check.
If your windshield is suspect, and i bet thats where its coming from, buy some "flowable silicone" to squirt under the gasket. that may do it, but the real answer is pulling the windshield, repairing the corners and gluing the windshield back in, being sure to use excessive amounts of glue.
