biz1285,
Sounds like an ongoing problem that some LR3's are having. Some have reported water coming through the A-pillar area and on to the floor, others have reported water coming through the light switches near the ceiling. Here's an excerpt from this forum from member JPTruck:
"...Back on subject of the leak near the windshield: I was on my way to the dealership this morning for 7500 mile service when I felt a drip on my left leg. There was water running down the "A-Bar," or whatever it's called (left side of windsheild, connecting dash to roof), and it was enough to cause a drip. The actual source was behind the plastic ABS tab. Lucky me, I guess that I was on my way in on a 32-degree rain day.
The service tech says that this is a defect in the LR3s which they are currently fixing on service calls. Apparently, there's a rivet hole along that A-bar that's not exactly water-tight and has no purposeful use to the car. The guy said it's a pretty easy fix, but I'd have to leave the car overnight. The gave me a rental, and off I went......"
There's apparently a LR Tech Bulletin regarding water ingress. Hopefully, your dealer can fix and replace any wiring looms if necessary.
