Re: [MBZ] Leaky 126 sunroofs

If the sunroof leaks, check for a deteriorated drain pan or plugged 
drains (all four corners, drains out the doorposts.  The sunroof 
"gasket" is a fiber faced thing, it does NOT seal out water.  The water 
is collected by the drain pan and drained out four plastic pipes to the 
ground.  If they are plugged, the headliner gets wet.
