[Shotimes] Moon Roof Leaking

[Kevin & Cheryl Airth]

John:
 A couple of more things. The moonroof does not really seal out the water at
all. If you look at the pan Mike talks about, you will see that it's made so
the water will flow into the pan or tray and out the 4 drain tubes faster
than it can drain in around the moonroof glass. So if it's leaking inside it
means the pan is full and overflowing.
 The rear drain tubes are much longer and harder to get at. Get under the
car and look behind (not in front of) the rear wheels. In the plastic fender
cover you will find a hole with a piece of rubber pointing down. The
passenger side will have 2 of these. The other one is for water drainage
from around the fuel filler door. You can see these tubes up and behind the
rear plastic bumper cover. These tubes connect to a rubber drain that is
self sealing. Poke a wire up into that as far as possible and see if you can
get any debris to fall out. You might unplug the plastic drain tube from the
rubber drain to make sure something is not stuck at that junction. When you
run water on the roof can you tell if you get 4 distinct streams under the
car? It's hard to tell but this is really the only clue to where you problem
is.
 I have a spare set of drain tubes if one of yours is cracked. Have never
heard of one cracking but the cars are old, so maybe so? Do not try to
remove the tubes if possible. They have plastic barbs to prevent them from
sliding around and are a hard to get at with out removing everything in the
way!
 One last thing. Sometimes if the car is sitting at an angle the water will
over come the drain tube in that corner. Not much you can do about that but
it's kind of rare. We get a TON of rain here in South Louisiana and ours has
never leaked yet!
