After fitting a new rear tailgate lock to my Wife's 03 K12 i have found that the wheel well seems to be collecting water. I have taken off the rear lights and noticed the foam seal that sits under each light is soaking wet, but I don't seem to be able to locate where the water is coming in from any ideas. One more thing the rear jet wash does not seem to be working the front ones are okay is this a known fault. Any ideas/suggestions for these two faults would be greatly appreciated.
