Default 987.1 Wiring Diagram
I found a blown 15A fuse in the rear fuse block but dont know what its for. Similar for the 2 other empty slots. Also, what are the relays for?

I'm working on a no brake light issue. PSM light is also on.

Replaced brake light switch and bulbs and contacts are good.

Thanks!

Found a diagram

Fuse 1 is for the engine compartment cleaner fan
2&3 are unused

the relays are for AC and air pump

IF the diagram is right

IIRC, there was only one fuse back there on my old '06 Cayman S.
