[W126 Coupe] Leaking Front end!

[Dick Spellman]

Hi Brad:

Start with the two roof drains to either side of the sunroof panel.  I'd 
look at these drains first where your complaint becomes more pronounced 
when wet weather is a factor.  When they are plugged you will get water 
and sometimes lots of it in the cockpit.  Sounds like you have a problem 
here because the roof needs to be retracted to access those two 
drains.   If you have a copy of the cd-rom manual handy, there is a 
section on sunroof mechanicals.  In any event, just an extension on a 
compressed air valve pressed into each drain should blow any debris 
clear.  You will hear the air escaping just behind each front wheel and 
behind the interior wheel panel once cleared.

Regards,

Dick
