I've been assembling all the parts to re-install heat in my teener, and now I'm down to checking out all the wiring. But I'm not getting any power to the rear heater fan (in engine bay).

I've cleaned up the connectors and wiring from the heater switch behind the shifter (ground side of the circuit). It comes out at pin #9 on the forward 14-pin connector on the relay board.

Power should be going to pin #11 of the same connector, but Im gettin zip.
This #11 connects to pin #10 of the lower-right 12-pin connector on the relay board - which bridges to pin #11 - then over to #87 of the relay.

I'm getting power at #30 on the relay - but don't have a way to check where its going from there. The relay is new, and I've swapped with others - but keep ending up with no power.

Any ideas - what I might be missing?

TIA,
