2003 C4 cab All four windows stopped working by the switches. They work fine when I put the top up or down. They do NOT work and neither does the top with the key in the door. The lock all doors switch does not work The passenger door does not lock. with the door key or the remote There is no fuse guide in the manual? Or on fuse door? How does one know what fuse goes to what? Any ideas?

You can google the fuse allocations and a graphic will show you what fuse goes to what. Just google "Porsche 996 fuses" and look through the images. Looks like you should check B6 and B8.

OK thank you. Its fuse C3 windows work and passenger door locks now! Weird that the passenger door lock is tied into the window fuse! There is no way to lock the passenger door with a key or by any other means if this fuse is blown!!
