Does anyone know what the possible/likely reasons the center vents
don't blow anything (hot or cold), but the side vents and the defogger

A recent engine rattle has been isolated to the air pump.  Bad clutch?
What's involved in repair, or are these swapped out?  Cost?
Can this be bypassed?

The sunroof pan on my 300TD leaks bigtime in the corners where it drains.
Can I get to these easily just by taking the pillar trim off to see what is
going on?  I can tell they are rusted looking at them from outside, but if I
can get to them easily perhaps I can repair them without ...

How did the Sindelfingen strike end up?
A report from IPS discusses how managements
tend to get big raises for being disloyal
to their workers:
