Not to be too persnickety, but a blown fuse should only be replaced once 
before serious investigation.  Each time it blows, you are subjecting 
your wiring to an extreme load.

Are *all* the parking light circuit lights not working, or just some?

There is a module in these cars that basically runs the "dimmable" 
bulbs, acting to take the load off the dimmer thingie.  It looks like a 
relay (double space), is probably in the aux panel over the drivers 
knees, and might be numbered 447 919 080.  Might be the problem...
