rain leaking thru a/c

[Tarheel]

I am getting prepared to go on top of a 95 excella and do an inspection for a rain water leak. I will remove the shroud and check for caulking problems as well as look for missing screws and other obvioius problems. Just wondering if anyone has had this problem, if its a common one and where did you find the problem and what is the fix. It leaked this weekend in a rain we had here in Virginia, not a driving rain and not a horrible leak, but one that needs to be addressed. Any ideas will be appreciated.

Not sure about the newer ones but the older ones had a drain line the exited in the wheel well. If the line gets pluged the unit would leak inside.
I had it happen to our AS. Cleaned out the line (with water hose) and that fixed the leak.
