Interior heater fan/blower not working - no power

[sweatyfox]

Hello,

Im having trouble with the interior fan blower not working, it was all fine till about a week ago and it just never came back on.

My car is a 1999 Boxster 2.5 (without A/C)

What I have tried so far:
1) Pulled out every fuse and they all looked fine.
2) Removed and tested the blower motor and that works perfectly.
3) Put a multimeter to across the power wires for the blower motor but got nothing, same with the resistor pack.

So I can safely assume there is no power getting to the fan/blower motor.

Where should I start looking next?
Is there a relay for this that might have died?

I’ve attached a few pics of the fuse box/relays.
Also I have no idea what fuse number the interior fan is supposed to be, so if anyone can point that out Id be grateful.

Thanks in advance,

SF
