Cooling fans - no power to relay or fuse box

[speeddevil68]

I have a newly acquired 2004 Boxster 986. I noticed that the coolant has boiled over in the past and the fans never ticked in when AC turn on - so all roads point to cooling fans.

Fans themselve work if I power directly, but not through the relay. Relay jumpered and still nothing. Measured voltage at the relay and I get 2v (I assume for all intents its unpowered). The fuse under the drivers foot well is intact, but similarly the voltage on the Red and Black (stripe) wire is 2v.

Please help with what I need to check next? I assume this red and black wire goes to the main power distribution fuses behind the glove box - how do I get to these without pulling heater box etc?

Any wiring diagrams would be greatly appreciated.

Thank you in advance for your help.

Just wanted to update, I have found the current distributor and removed it to find the fuse has indeed blown. This explains why my cooling fans aren't working. I will now progress to understanding why the fuse blew in the first place.
