Hard to say but guessing it has something to do with your lamp assy, it is possible the seal between the lens and the lamp body could be broken and also there should be a gasket between the lamp itself and the body,you could try a used lamp from a scrappy, if they are a decent lot they would let you try it and see if it cures your problem.
