OK All,
still chasing leaks.

Now I have a leak that comes down the trim panel just ahead of the
passenger door.  I took out the glove box and still cannot guess where
it is from.

I have traced it as far up as the nylon arm on the air distribution
thingamabob.  (the arm moves back and forth when you switch between
closed circ and open circ.)

Yesterday I removed the black trim piece under the wiper arms.  I do not
see a place where it couldfd be coming in at the base of the
windshield.  That all looks well sealed.  I applied silicone sealant to
any thing that looked even remotely like it might leak.  But today it
rained and it is still leaking.

I have covered the entire roof seam on the pass. side with silicon.  I
have also siliconed the entire windshield surround..all with no change
in leakage.

Anyone solved this one before?

Norman.
